Mary Trump said that her uncle is scared after former White House counsel Pat Cipollone testified.
"To say that Donald is terrified is correct and also an understatement," Trump said.
This could be the first time in his life that he can't deny the walls are closing in. She said there was a lot of evidence coming out of the hearings.
The witnesses that are coming forward to speak with the committee are important in terms of access and positions in his administration.
The details of Cipollone's testimony have not been made public.
Trump criticized Cipollone in front of the panel, arguing that it could discourage future presidents from having conversations with the White House counsel.
She said that he didn't attack Cipollone personally, as he has been known to do with other witnesses.
The former acting United States Solicitor General believes that Trump is trying to keep Cipollone on his side.
Donald Trump lashes out when he's scared, but when he's terrified, he tries to butter him up.
According to legal experts, Cipollone's first-hand account of whether Trump was aware that he was engaging in criminal activity could strengthen a case against him.
On Friday's show, Phang asked Trump about her uncle's legal troubles, including the Fulton County District Attorney's probe into alleged attempts to overturn the 2020 election in Georgia.
Mary Trump said it would be "almost unimaginable" if he got out of all the charges against him.
The only reason I'm not confident is because he has always been on the ice. Hopeful but not certain of the consequences.
The strongest cases against him were in Georgia and New York, she said.
