Story highlights "I've never come a situation where Mr. Trump has said something that is not accurate," Cohen said

Cohen brought up posts on social media from people also claiming to have seen what Trump did on 9/11

Washington (CNN) A top counsel for Donald Trump on Monday defended the Republican presidential front-runner's claims about the September 11 attacks during a spirited exchange with CNN's Jake Tapper.

Following his boss' refusal to back down from claims that he saw "thousands of people" in New Jersey cheering in the immediate aftermath of the September 11 attacks, Michael Cohen sparred with Tapper on "The Lead."

Cohen did not back down despite being confronted with the lack of evidence of Trump's September 11 claim.

"I'm not so sure that that's true, and I've worked for Mr. Trump now for a long time," Cohen said. "I can tell you that Mr. Trump's memory is fantastic, and I've never come a situation where Mr. Trump has said something that is not accurate."

Cohen brought up posts on social media from people also claiming to have seen the same thing as Trump and also pointed to what he called the media's failure to refute Trump's claims.
