Michael Cohen, former Trump ally and attorney, slammed former President Trump’s sons’ recent testimony in the New York civil fraud trial.

Cohen joined MSNBC’s Ali Velshi to talk about the former president, his sons and the ongoing fraud trial that he previously testified in.

Cohen said he believes both Trump children lied under oath and are “emulating their father.”

“I mean, the guy lies the way you breathe, and the kids are doing the same thing,” Cohen said about the former president and his sons, Donald Trump Jr. and Eric Trump. “How stupid do they have to be?”
