CNN anchors Poppy Harlow and Jim Sciutto grilled Rep. Ilhan Omar on Thursday about a tweet she made suggesting that Sen. Lindsey Graham is being blackmailed by the White House. "They got to him, he is compromised," Omar tweeted Wednesday in response to a video of Graham denouncing Trump in 2015. <blockquote class="twitter-tweet" data-lang="en"><p lang="en" dir="ltr">They got to him, he is compromised! <a href="https://t.co/m8sB3EmElg">https://t.co/m8sB3EmElg</a></p>— Ilhan Omar (@IlhanMN) <a href="https://twitter.com/IlhanMN/status/1085338922169831426?ref_src=twsrc%5Etfw">January 16, 2019</a></blockquote> <script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script> "The evidence really is present to us. It’s being presented to us in the way that he is behaving,” Omar claimed when asked for evidence. "But that’s not evidence," CNN's Harlow replied. "That’s your opinion. But now as a sitting member of Congress, you have tweeted, 'they got him on this.' Again, just based on what evidence?" "My tweet was just an opinion based on what I believe to be visible to me, and I’m pretty sure there are lots of Americans who agree on this," Omar eventually said. <blockquote>REP. ILHAN OMAR: So, over the last three years, we have seen many times where Sen. Lindsey Graham has told us how dangerous this president could be if he was given the opportunity to be in the White House, and all of a sudden he’s made a 360 turnaround. I am pretty sure that there is something happening with him, whether it is, you know, something that has to do with his funding when it comes to running for office, whether it has something to do with the polling that they might have in his district [sic], or whether it has to do with some sort of leadership within the Senate. He is somehow compromised to no longer stand up for the truth and is fighting to protect the oath that he took in serving the American people. JIM SCIUTTO, CNN: That's quite a charge to make, you say you're "pretty sure." Based on what evidence? What facts? That is a remarkable comment to make about a sitting U.S. Senator. OMAR: The evidence really is present to us. It’s being presented to us in the way that he is behaving. POPPY HARLOW, CNN: But that’s not evidence. That’s your opinion, but now as a sitting member of Congress, you have tweeted, 'they got him on this.' Again, just based on what evidence? OMAR: My tweet was just an opinion based on what I believe to be visible to me, and I’m pretty sure there are lots of Americans who agree on this.<blockquote>
