'Allergic to telling the truth': Legal expert says Trump family is in trouble in fraud row

Donald Trump's entire family has a difficult time telling the truth, and that could come back and bite them in the ongoing civil fraud trial in New York, according to an expert on legal matters.

Appearing on The 11th Hour with Stephanie Ruhle on MSNBC late Thursday night, Neal Katyal said, "This is a family that is really, I guess, allergic to telling the truth." Katyal is the former acting solicitor general.

Katyal specifically pointed out that next week will be the biggest problem for the Trump family.

"The entire basis of this case is that they lied about their assets, and so I think the next week, when each of the Trumps is going to have to swear in and tell the truth under penalty of perjury, is going to be a very tough time for the Trump family," he said. "With respect to Don Jr. and what he says, two possibilities, either he's choosing to mislead the judge, the public about his business knowledge, or he came awfully close during I guess flunking out of Wharton -- because it's really convenient how Don Jr. seems to have forgotten information that could be damaging to him, as you've said in the lead up to the segment before the interview. And it kind of looks like he's intentionally decided to play dumb here, which might be a nice change of pace for him."
