Elsewhere, including the withdraw of u. S. Troops in syria, abandoning a longtime ally of the u. S. , the kurds, and the announcement trump plans to use his own resort in miami to host the g7. And finally, the admission that there was a quid pro quo when the u. S. Withheld ukraines military aid. That admission came from trumps acting white house chief of staff, Mick Mulvaney, who later tried to walk it back. But hes on video saying one of the reasons the white house withheld ukraines military aid was to get ukraine to investigate democrats. Cnn White House CorrespondentJeremy Diamond joins us now. Mick mulvaney has a meeting today at camp david. Is impeachment on the agenda . Thats the story consuming washington right now, particularly the white house and capitol hill. Mick mulvaney, the acting chief of staff, has now put himself at the center of the latest developments on that storyline, with that stunning admission a couple days ago from the White House Briefing room podium that there was indeed some kind of quid pro quo, that at least the reason for withholding that security aid was in part being driven by the president s desire for ukraine to investigate democrats as it relates to the 2016 election. But of course, ana, there are other issues also on the table, particularly because a series of decisions by the president in the last week have really sparked some concerns among republicans in congress, namely so beyond the impeachment inquiry, you have the president s decision in syr syria as it relates to u. S. Troops there. Then you have the president s decision to hold the g7 next year, which is slated to be in the United States, at his own property in miami, florida. The white house still insisting that that property was simply the best one that they could possibly find to host that g7 summit. Ana . And to think that was just a couple days ago. Seems like light ages away from what we learned that announcement. Thank you, Jeremy Diamond, at the white house for us. It all started with a promise. At some point, im going to be so president ial that you people will be so bored, and ill come back as a president ial person, and instead of 10,000 people, ill have about 150 people and theyll say, but boy, he really looks president ial. Remember that . So president ial, at some point. Well, this week marked 1,000 days of the trump presidency. And what did we see . We saw the president of the United States go on twitter and rail against the speaker of the house as having something wrong with her upstairs after a meeting on syria descended into name calling. What i witnessed on the part of the president was a meltdown, sad to say. He called her a thirdrate politician. This was not a dialogue. It was sort of a diatribe, a nasty diatribe not focused on the facts. We saw the reports. He referred to his own former defense secretary, jim mattis, as the worlds most overrated general. Im honored to be considered that by donald trump because he also called Merrill Streep an overrated actress. So i guess im the Merrill Streep of generals. We saw the fallout from the president s sudden decision to pull u. S. Troops from Northern Syria. The invasion by turkey, the killing of the kurds, the escape of isis prisoners, and a land grab by syrias dictator, bashar al assad, and his enablers, russia and iran. And we saw a president who wants us to believe everything was fine. So i view the situation on the Turkish Border with syria to be for the United States that ste strategically brilliant. We saw the extraordinary letter he sent just three days after his phone call with the president of turkey, a letter that included linines like, let work out a good deal, dont be a fool, ill call you later. This had such an adolescent quality to. I immediately called my Research Assistant and said, see if this is fake. This letter he handed out to all of us at the beginning, which if he hadnt handed it out himself, i would have thought was not a real letter. And we saw the white house admit that, yes, the president did hold up aid to ukraine because he wanted them to investigate political opponents. And i have news for everybody. Get over it. Theres going to be political influence in foreign policy. Thats going to happen. Elections have consequences. Oh, and in the middle of all that, we saw the president decide that the best place in the entire United States to hold next years g7 summit was at his own property. Trump national in doral, florida. So we come back to where we started. Im going to be so president ial that you people will be so bored. Are you bored yet . With us now to discuss, cnn politic political commentator, s. E. Cupp. Also, bill crystal. S. E. , you wrote in an oped this week. Yeah, only one thing has had the ability to unlock the vice grip trump has held on congressional republicans. Wasnt russia. Wasnt ukraine. It wasnt tariffs. It wasnt some of his personal pick dill lows. It wasnt some potential criminal activity. It was syria. Whether it was last year in 2018 when republicans very vocally, immediately, and almost in unison came out against his threats to quit Northern Syria at the time or now. 129 House Republicans voted against President Trumps withdrawal from syria. Thats stunning. And you have to take you have to take note of that. Okay, if this is an issue around which so many republicans have suddenly found a backbone and are this comfortable calling him out, it must be really, really bad. So im not sure that this wont be a turning point. If you were a republican who may be on the fence, may be secretly thinking, i dont know how much more of this guy i can take, well, this might just be your excuse to break ranks. Bill, yes, there was syria, but what Mick Mulvaney said at the white house podium seemed to be enough for at least one republican lawmaker to announce publicly hed be open to considering impeachment and former gop Governor John Kasich said it was the final straw for him. Listen. Youre saying at this point youre not ruling out the possibility this is an Impeachable Offense for the president. I dont think you could rule anything out until you know all the facts. If youre asking me if i was sitting in the house of representatives today and you were to ask me, how do i feel, do i think impeachment should move forward and should go for a full examination and a trial in the United States senate, my vote would be yes. Bill, do you expect to see more of this . I think they should be. I wouldnt overstate the odds. Theres a ridiculous resolution thats been introduced in the house by a republican condemning adam schiff. To scensure him. Really bizarre. 120 republicans have cosponsored it. Such a ridiculous gesture. Its silly and really offensive almost. But that means 27 republicans havent. Thats 27 republicans resisting peer pressure on an issue thats directly related to impeachment since thats what schiff is being censured for. I think mulvaneys thing is very interesting. I was thinking, why is mulvaney not doing what every white house spokesman does, deflecting . He was in the middle of it. Who was the person that held up the military aid . The Defense Department had the list done. Everyone was circulating this around the government to make sure it was done correctly. Then suddenly it gets stopped in the white house. Mulvaney stops it. They get no explanation. The Defense Department is so worried that this is illegal because if Congress Appropriates the funds, youre supposed to give them out. They have the Defense Department general counsel write a memo saying he doesnt know whats going on. The Defense Department has done its best. So that was mulvaney. Mulvaney knows. Why is he so angry there and sort of arrogant instead of just trying to deflect the issue . Because mulvaney was in the middle of it. He knows why he stopped that military aid. Because donald trump told him. And what donald trump said to him was not, you know, ive suddenly discovered a great interest in the overall problem of corruption in ukraine, and we need to really use this as leverage. He told hip, look, that investigation into the bidens isnt going toward as giuliani wants and so forth. Stop the aid. I think the mulvaney thing is an important moment that shows how clear the inappropriate action by the president was, and it was by the president. This isnt one of those issues where it was someone else did something and maybe the president knew about it. Maybe the president condoned it. It was the president. And so on one hand, you see some vulnerability now within the republican ranks breaking potentially with this president. Yet, you know, congressman rooney, who we heard alongside kasich, rooney Just Announced hes not seeking reelection. Then kasich, when i pushed him, asking are you saying should he be removed from office, he wouldnt go there. Yeah, were not there yet. We are not at breaking point. Thats clear. But again, i think this confluence of events, these pressure points for republicans, hes almost taunting republicans. Every time he goes out and says something in politic, and worse than in politic, celebrating turkeys ethnic cleansing of the kurds. Every time he says Something Like that, hes daring republicans, leave me now. Are you ready . Is this the time . And it just so happens that that mechanism is currently on the table. Its impeachment. And again, when you take a vote for impeachment, you dont have to raise your hand personally and say, it was this, this was my breaking point. So who knows. All of this is happening at once. And if youre a republican, again, whos maybe a little hesitant, theres so many excuses now, good reasons now for you to really think seriously about this in a way that i dont think a lot of republicans ever had through mueller, through russia, even ukraine. I think they were like, well, this is bad, but this isnt impeachable. And this is partisan. When it comes to syria, i think this was a bridge too far finally. I have to ask you about the bizarre feud between Hillary Clinton and congresswoman Tulsi Gabbard and jill stein. Clinton saying gabbard is a favorite of russia. She said stein is a russian asset, to which stein replied this way. No, i am not a russian spy. I think this is a completely unhinged Conspiracy Theory for which theres absolutely no basis. In fact, not for myself and not for Tulsi Gabbard, i think its really outrageous that Hillary Clinton is trying to promote this crazy idea. You know, you cant just slander people. You have to present some basis in fact. Bill, does this sort of side show just play into trumps hands . In a way, it clinton acting like donald trump by spouting conspiracy theories . Well, to be fair to Hillary Clinton, she said correctly that Tulsi Gabbard is a favorite of putin or assad, certainly. Doesnt mean shes a spy or an asset. Jill stein, i dont know, she hung out with putin. Trump immediately defended jill stein. I was struck by that. Maybe Hillary Clinton should have been a little more careful. I think it was an offthecuff remark. I dont think it changes anything. But the bringing together of syria shows the real world consequences of having donald trump as president and having him liberated, really. Theres no jim mattis. Theres no none of the senior people who were there in the first couple years whom republicans could tell themselves, you know, trump is a little wacky. He wants to do illegal things, but don mcgahn stops him and Jeff Sessions stops him. No one stops him. So syria shows the realworld consequences of trump unleashed here at the end of a thousand days of his presidency. Doral shows the incredible brazenness of the corruption. And ukraine shows genuinely, i think, illegitimate use of u. S. Foreign policy for plolitical ends. S. E. , final thought . The Hillary Stein tulsi thing is so bizarre. For hillarys part, so unwise. I dont think she needs to make these outlandish i mean, bill is right. Tulsi is a favorite of russias and certainly assads, but she doesnt have to go this far. It feels to me like hillary is sort of in burn it down mode. Just burn it down. I mean, her aides are, you know, giving these cute, you know, kind of responses. Well well, if the nesting doll fits. I mean, how does this help the democrats in any way . It doesnt. It doesnt. And you have to be wondering if youre a front runner i mean, tul tulsi is polling at 1 . Hillary elevating her almost. If youre a real front run we are a chance of winning, i think youre worrying that hillary might be unhelpful in this as this thing goes along, if she continues wading in like this. All right. S. E. , bill, good to have both of you here. Tomorrow, jake tapper will interview congressman frances rooney. That will be on state of the union at 9 00 a. M. Just ahead, Bernie Sanders hosting his first rally since recovering from a heart attack and receiving one of the most coveted endorsements in the party. Why alexandria ocasiocortez says sanders is the candidate to beat President Trump. Youre live in the cnn newsroom. Bernie sanders is pushing past his recent health scare. The democratic president ial hopeful headlined a rally in new york today almost three weeks after his heart attack. He officially received the endorsement of one of the partys rising stars. When the federal government decided to discriminate and abandon my queer family and friends, Bernie Sanders was putting his career on the line for us. Cnns ryan nobles joins us from queens, new york, where that rally took place just a couple hours ago. Ryan, whats your big takeaway there today . Reporter i think the message here was loud and clear, ana. That is bernie is back. He said that many times. That was the hashtag that was trending on twitter today. What was interesting, ana, was that sanders did not back away from these questions about his health. He wanted to make it clear to everybody that was here at this packed park and people watching at home that he is up to this challenge, that his health is okay, and that he can handle the rigors of a campaign and the presidency. Take a listen. I am happy to report to you that i am more than ready. More ready than ever. To carry on with you the epic struggle that we face today. I am more than ready to assume the office of president of the United States. Reporter sanders will get back on the campaign trail in a big way. He heads to iowa later this week. That caucus set to take place in a little more than a hundred days. Sanders still has 30 million in his campaign war chest. He is someone that will still continue to be a force to be reckoned with in this democratic primary. Ana, those questions about his health will certainly linger, but sanders did his level best to try and get past them here in this huge rally today, the biggest rally of his campaign to this point. Showing vibrancy, energy, and obviously his signature passion. Ryan nobles, thank you for that reporting.
