Brian ross finds him today. Did you give them documents . Did you receive documents from them . And, two separate manhunts. The officer killed showing up to work. And in atlanta, the female lawyer targeted and killed during rush hour. New reporting tonight. Good evening. Its great to have you with us on a tuesday night. Were going to begin tonight with the images that have stunned the world. Its hard to imagine that after six years of war in syria, there could be something even worse than what many have already seen. Tonight, our team has taken great care to pour through the images first, but we warn you, theyre still difficult to see. A chemical attack. So many families and children among the victims. Survivors being sprayed off, after war planes dropped what appears to be a toxic gas. The white house responding. Heres jonathan karl. Reporter tonight, outrage over these scenes of horror and suffering in syria. An apparent war crime, a suspected sarin gas attack by the government killing dozens and sickening many more, Young Children among the victims. Rescue workers desperately work to wash the chemical from the victims. Children clinging to life, struggling to breathe. The gas attacks are continuing every day and no one is doing anything to stop this gas attack. Reporter this attack following two chlorine gas attacks over the past week. While this local activist reported from one of those hospitals, it was hit with another airstrike. The white house called the attack reprehensible and said it cannot be ignored by the civilized world. But the statement also took aim at president obama. These heinous actions by the Bashar Alassad regime are a consequence of the past administrations weakness and irresolution. Thats a reference to president obamas failure to punish syria for crossing the socalled red line when it used chemical weapons in 2013. President obama in fact boasted that he had worked out an agreement with russia and syria to get rid of assads chemical weapons. Assad gave up his chemical weapons. Thats not speculation on our part. Reporter tragically, that was not true. At least some of the weapons remained. The big question right now is whether President Trump will hold assad accountable for using chemical weapons. He didnt talk about it today but he did say this in a speech on the economy. Im not, and i dont want to be, the president of the world. Im the president of the united states, and from now on, its going to be america first. Reporter secretary of state Rex Tillerson ignored questions on the attack. Mr. Secretary, any comment on the chemical attack in syria . Bashar al assad should still be president of syria . Reporter but just last week tillerson signaled a significant change in longtime u. S. Policy that Bashar Alassad must go. I think the status in the longer term status of president assad will be decided by the Syrian People. Reporter tonight, these Syrian People arent determining the status of assad, they are trying to survive his brutality. And jon with us live tonight from the white house. Secretary tillerson did not take questions on this today, but he appears to have taken to harsher line in a Statement Today than just last week . Reporter a much harsher line. A written statement where he condemned assad. Referring to his brutal, unabashed barbarism. And his fundamental disregard for human decency. And called out russia and iran, saying they bear great moral responsibility for the attacks. But its unclear what the Trump Administration will do about it and whether they now want assad to go. Jon, thank you. We turn to the other major headline involving the white house, after President Trumps claim that president Obama Wiretapped trump tower. Susan rice answering questions tonight. Did she ask that members of the trump team were unmasked after being swept up in surveillance on foreign threats . Heres cecilia vega. Reporter it was exactly one month ago that President Trump accused president obama of wiretapping him in trump tower. And tonight, the president s conservative allies say obamas former National Security adviser susan rice revealed the identities of Trump Associates swept up in surveillance. From rice today, a firm denial. This is not anything political has been alleged. The allegation is that somehow Obama Administration officials utilized intelligence for political purposes. That is absolutely false. Reporter sources tell abc news that as the Intelligence Community investigated russias election meddling, in some cases, Trump Campaign and transition officials were picked up in surveillance. Rice requesting their identities. Today rice said she did indeed ask to know names. A request known as unmasking, done in cases where u. S. Security is at risk. American identities that would otherwise be anonymous are revealed to those with security clearance, like rice. In order to understand the importance of the report, and assess its significance, it was necessary to find out, or request the information as to who that u. S. Official was. Reporter rice wouldnt say whether any of those names were Trump Associates and she vehemently denied that she leaked any names. I leaked nothing to nobody and never have and never would. Reporter and says the unmasking was a key part of her job. We cant be passive consumers of this information and not and do our jobs effectively to protect the american people. Imagine if we saw something of grave significance that involved russia, or china, or anybody else, interfering in our political process and we needed to understand the significance of that. For us not to try to understand it would be dereliction of duty. Reporter republicans, not buying it. Senator rand paul tweeting, smoking gun found. Saying so now we know that someone in the Obama Administration was eavesdropping and specifically searching a databank looking for the trump people. No. No. Thats a big deal. Reporter rice maintains there was nothing illegal, no smoking gun, and no wiretapping of trump tower. There was no such collection or surveillance on trump tower or trump individuals and it is very important to understand, and by that i mean directed by the white house or targeted at trump individuals. Lets get to cecilia vega, and some republicans are calling for rice to testify. Where does the white house stand . Reporter theyre not weighing in on this one just yet. They do, though, call the reports about unmasking troubling, but the calls growing louder. The republicans just sent a letter to the senate and house intelligence committees demanding that rice be called upon to testify. Cecilia, thank you. We turn now to an abc news investigation, and it involves former Trump Campaign adviser carter page. And this question did russian spies try to recruit him to work for them . Tonight, the evidence, and how he answers when brian ross tracked him down today. Reporter two years before this new york businessman, carter page, became a Foreign Policy adviser to candidate donald trump, russian spies tried to recruit him as an intelligence source. Fbi documents show they offered page, identified as male number 1, favors and Business Opportunities in russia in exchange for information. He flies to moscow more often than i do, one russian spy told another about page. Its obvious that he wants to earn lots of money. You promise a favor for a favor. The spies, posing as russian trade officials, said page provided them with documents on the u. S. Economy. Today page told abc news that any documents he passed to the russians were of little consequence. Any information i would give is, is, again, immaterial. And all public information. Reporter did you feel like you were working for them as an intelligence source . Of course not, of course not. Reporter thats what they call you. Its ridiculous. Reporter whats ridiculous about it . Everything. Making it up again. Nothing. Good to see you. Reporter russias interest in page continued during the campaign. Last july, the littleknown businessman was invited to deliver a prestigious speech at a Moscow University where he denounced the Obama Administration. But page has said allegations he served as a gobetween for the kremlin and the Trump Campaign or met with senior russian officials are false. Completely made up and reporter never happened . Absolutely never happened. Yeah. Reporter but since that interview, page has acknowledged he did meet with the Russian Ambassador at the Republican Convention in cleveland. White house aides say page was never a major player in the campaign. And the russian spies who tried to recruit him are now back in moscow. Brian, during the campaign, american intelligence officials became concerned that page was advising donald trump . Thats right, when he showed up in moscow to give the speech last july, it only added to their concerns about the possible russian connection. Brian, thank you. Meantime on capitol hill, the new effort to repeal and replace obamacare, take two. President trump reportedly hoping for a vote now by the end of the week. Intense meetings taking place with some conservative republicans who stopped the deal last time. But could preexisting condition coverage be going away in this new replacement . Heres mary bruce. Reporter on capitol hill today, Vice President mike pence stepping in to Bring Health Care reform back from the dead. Is healthcare going to get done this week . What makes this time any different . The white house is now trying to strike a deal with the freedom caucus, those ultraconservative members who killed the first bill. President trump attacking them ever since. But now, eager for a win, the white house seems to be putting on the table something the president vowed not to touch. When you replace it, are you going to make sure that people with preconditions are still covered . Yes. Because it happens to be one of the strongest assets. Reporter today, the white house is considering effectively doing away with that provision. People with preexisting conditions could see their Health Care Costs skyrocket. Also on the chopping block, the requirement that Insurance Companies cover essential benefits like wellness visits, Mental Health treatment, Maternity Care and even ambulances. Now, individual states could opt out. So, is healthcare reform back on . Yes, it is. Reporter republicans know the clock is ticking. With members about to head home for two weeks, they could be facing more of this. If you yell one more time like that, im going to ask you [ booing ] reporter still, tonight, no agreement. Its premature to say where we are or what were on, because were at that conceptual stage right now. Mary, are moderate republicans going to be onboard this time . Reporter the republicans are facing the same balancing act that derailed them the first time. Any concessions to conservatives risk alienating the moderates. The Vice President is back here on capitol hill tonight meeting with republican leaders. Theyre eager to get this done. Mary, thank you. Also this evening, ivanka trump answering criticism about her involvement with her fathers administration. Taking on an official role at the white house as an assistant to the president. In an interview with cbs news, asked whether shes complicit with his policies, heres what she said.
