Democratic frontrunner as a challenger is making a move. If iowa is the key to the democratic nomination, is it up for grabs . Hello, im jake tapper in washington where the tate of the union issen meshed in another scandal involving a foreign leader. President trump is defending himself as his administration is facing an uproar over new reporting that he presses ukraines president Vladimir Zelensky eight ways according to the wall street journal to investigate joe bidens son during a phone call on yul 25th. President trump minutes ago told reporters that that call was largely congratulatory and, quote, a perfect ten. And again, this morning, the president raises questioned about former Vice President biden. We should note according to the cranan prosecutor there is no evidence of any wrongdoing by either joe or hunter biden. And another known, the president has not denied and continued to not deny this morning that he discussed the former Vice President in his call with the ukraine leader. The issue of the president pressuring ukraine to investigate his rival came to light as part of a whistleblower complaint that the white house is keeping from Congress Much to the chagrin of the Inspector General for the Intelligence Community. The president has also gone from tweeting that, quote, virtually any time i speak on the phone to a foreign leader i understand there may be people listening from various u. S. Agencies to this weekend quoting a fox personality saying, quote, an american spy in one of our intelligence agencies may have been spying on our own president. All of this has set off a fight between the white house and congress. The new allegations are already animating the 2020 campaign trail. And reenergizing democratic calls for impeachment on capitol hill. This week President Trump is preparing to step on to the world stage and headed to new york for the United NationsGeneral Assembly gathering of World Leaders where he is expected to meet wednesday with ukrainian president zelensky facetoface for the first time. Joining us now to talk about this and much more, treasury secretary Steve Mnuchin heading with the president to the United Nations. Thanks so much for being here. Appreciate it. Great to be here with you. I want to start with the president s interaction with ukrainian president zelensky, were you aware the president had pressed zelensky to investigate the bidens in. I was not on that call, so im not aware. But ive been plenty of other calls with the president. There is other people who listen to these calls. So i dont expect there were any issues whatsoever. Is it common for the president , you say youve been on other calls with him, to press foreign leaders to investigate his political rivals here in the United States . Is that something youve heard before . I havent heard that and i think youre speculating on what the president said. I would say these are confidential discussions between two foreign leaders but i think the bigger issue is biden came out this weekend saying he never had any discussions with his son. His son came out and said he had had business discussions with his father so i think that the real issue is not what the president said, but what, indeed, did bidens son do. The one i think what youre referring to is that in a new yorker story a few months ago hunder biden said they talked about it once and it was just joe biden saying to him i know you know what you are doing. So that is the issue here. But the reason you say it is speculative, but the wall journal and the Washington Post have both reported on the contents of the call and there is a whistleblower trying to bring attention to this to congress and just as a general premise, is it okay with you for a president , any president , to pressure a foreign leader, a foreign leader that wants hundreds of millions of dollars in aid to investigate a political rival. Is that acceptable . Youre speculating that the president pressured. I dont have any reason to believe that the president pressured you brought it up many times. Again, youre speculating. It is not speculating. It is in the Washington Post and the wall street journal. So everything in the Washington Post and the wall street journal we should assume is factual. So how many times did he bring it newspaper again. Im not aware. I wasnt on the call. Given everything going on this week in iran and everything around the world i find it interesting there is so much interest in this story when again there are a lot of people who listened to this call. It wasnt a secret that one person was on and said something. Again, people know there were issues that bidens son did business in ukraine. I, for one. Have concerns about that but there is no issue here. I was in principle meetings when we discussed foreign aid to ukraine. Nothing ever came up there was any link or anything else. I think things are being implied though dont exist. Well the reporting is that President Trump in this phone call in july brought up the need for ukraine or his desire for ukraine to investigate hunter biden and joe biden. Nobody has denied that is the case. There is a whistleblower who wants to bring this information, he has a whistleblower complaint to congress and the white house is preventing that. If there is really nothing there, why shouldnt the white house just let congress let the gang of eight, the Intelligence Leaders of the house and senate and look at the whistleblower complaint and if it is as innocent as you say that would clean it up. That is a terrible precedent. Conversations between World Leaders are meant to be confidential and if ever time someone for political reasons raised a question and all of a sudden those conversations were disclosed publicly, and when you dus close them to congress, a lot of times they leak into the press. Then why would World Leaders want to have conversations together. So the real issue here is this was an important week. It is a very important week. What went on with iran, the maximum Pressure Campaign. This is a conversation between two World Leaders with plenty of other people who were on the call. And i want to ask you about the maximum Pressure Campaign in a second but i need to understand, is it the position of the administration that it is acceptable for politicians to pressure foreign leaders to look into and investigate political rivals because that is what is being said, being reported happened on this phone call and it alarms a lot of people. I wasnt on the call but i have no reason to believe that the president pressured or anything else any foreign leader. This was largely a congratulatory call and theyll be a meeting this week and i think this is a lot being made up about one persons speculation. And again, this isnt the first time when the president has been attacked and things have turned out to be incorrect. Are you going to be at the meeting with President Trump and president zelensky. Yes, i expect to be at the meeting. If President Trump brings up this desire of his to have the ukrainians investigate the bidens and again the ukrainian prosecutor said on the record and the Ukrainian Foreign minister said there is nothing there and they did look into it and there is no evidence of wrongdoing and if president brings it up will you Say Something and say i dont think that is appropriate. My conversations between the president and i are confidential. But let me just say, i find it interesting that we spend close to 7 1 2 minutes talking about a political issue and not talking about what is the real issue of the week. Which is iran launched an ata launched an atalk on saudi arabia and on the World Economic system and it is a very significant issue. That is really been our focus this week. Well, i do want to talk about that. But let me just close by asking, if, for instance, president obama had pressured a foreign leader, putin or the president of ukraine, anyone said i want you to look into donald trump jr. Or eric trump, international businessmen, both of them, would you not find that inappropriate. Im not going to speculate on that. What i do find inappropriate is the fact that Vice President biden at the times son did very significant business dealings in ukraine. I, for one, find that to be concerning and to me that is the issue perhaps that should be further investigated. I dont understand. So it is okay for donald trump and eric trump jr. To do business all over the world and okay for ivanka trump to have copyrights while President Trump is president and while joe biden is Vice President his son shouldnt be able to do business dealings . Again, i dont want to go into more of the details other than to say well youre setting a precedent that the president is violating. Again, i think there is a significant difference in what youre saying, okay. What i was saying between biden and his sons relationship with the ukraine oligarch and potential business dealings that the Trump Organization has had which predated his presidency. Just again, to underline the ukrainian prosecutor said there is no evidence of any wrongdoing but i know you want to talk about iran so let me ask you, you announced on friday the u. S. Is implementing sanctions that would cut off Irans Central Bank and National Development fund from the u. S. Banking system. You said that with those sanctions the administration has, quote, cut off all sources of funds to iran. Does this mean at this point in a the Trump Administration has exhausted its ability to sanction iran or are there still other avenues . I think there are some other avenues . I think weve now cut off all of the money. The thing were focusing on now is people that are violating the iran sanctions and issuing sanctions on third parties where we see violations. Including people in allied countries like the u. K. Or germany or france. If they violated, absolutely. Anybody attached to the u. S. Dollar system will abide by the sanctions. Let me ask you. Because thief been doing this maximum Pressure Campaign on iran for more than a year but it seems like tensions are worse than theyve been in a long time. Are you confident that it is working . Well i think the tensions are as you said are worse because it is working. As you see weve cut off all of the money to iran. I think you see iran acting in desperation, attacking its neighbors. This is really unprecedented in that sense. And, yes, we continue to have conversations with all of our allies about these issues. And well be having conversations at the u. N. This week, this is a major topic for the president. President trump has said hes willing to meet with the iranian president rouhani. Does that still hold true now even given the latest iranian provocations . Well i think the president has always said he would leave the door open but i think it is highly unlikely given the current circumstances. I do want to ask you about the u. N. Yenl assembly and the president is not attending the Climate Summit tomorrow and this is the second gathering of World Leaders to talk about the topic that the president has skipped in the last two months. Do you think the Climate Crisis is a global threat . Well, what i think is important and is the environment and what is important is clean air and clean water. The u. S. Is very far advanced in clean energy, natural gas. So if you look at kind of our environmental record, it is actually quite good. The concern is what is gone on in the environment in other parts of the world. And yeah, so, to that end, looking at peerly at economic impact, because your area of emphasis a study found that the Climate Crisis if it remains unaddressed as it is today, could cost the United States up to 10. 5 of gdp by 2100. Is this not a serious threat . I find there is a lot of assumptions and lots of speculation in those numbers so i dont for one think theyre real. You think that National Bureau of Economic Research study on in on this is not real . Again, there are a lot of assumptions that go into those conclusions. So, no, i dont support that outcome. But what i do think is important and this is an important issue, we are very focused on clean air, clean water, clean energy. The u. S. Technology has made major progress in these areas and the reason why the president got out of the paris deal is because it was an unfair deal for the u. S. Relative to the rest of the world. If your emphasis is on clean air, why are you not allowing california to set its own Environmental Standards . You say that you your emphass on clean air but you are not letting states like california what they want to do when it comes to clean air. These are complicated issues. California shouldnt have separate rules. I think that is the issue. I, for one, drove an electric car in california. But let me just say, electric cars also create issues with batteries and how you dispose of batteries. These are complicated issues. But i think the issue is california is part of the United States and there shouldnt necessarily be separate standards. I would say i think climate scientists are near unanimous position that much more needs to be done in the Trump Administration is not focusing on it. Steve mnuchin, the treasury secretary, good luck at the u. N. Assembly this week into President Trump just took questions on the uproar over his call with ukraines president and well play that for you next and let the president speak and intel chair adam schiff will join me to respond and could joe biden lose iowa and still win the nomination.
