Bob Woodward shared more details from an episode between President Donald Trump and his former lawyer John Dowd, in which Dowd pulls no punches in telling Trump why he can’t sit down with Special Counsel Robert Mueller.

According to Woodward’s book “Fear,” Dowd told Trump that he’d be “fitted for an orange jumpsuit” if he testified.

“Trump goes ballistic, makes things up, starts screaming- Dowd thought had he been Mueller, he would have been fired right on the spot,” Woodward told late night host Stephen Colbert on Monday. “‘You can’t testify. You- you are disabled.’ I mean, imagine the lawyer- your lawyer, telling you you’re disabled. ‘And you can’t testify because you can’t tell the truth. You just make things up!’”

As Woodward writes to end the book: “Dowd knew he couldn’t bring himself to say to the President, ‘You’re a fucking liar.’”

Dowd left Trump’s legal team in March.
