President Donald Trump proposed eliminating judges multiple times, the senior administration official, known as “Anonymous,” claimed in a soon-to-be-published book A Warning, according to Axios.

Axios on HBO aired a preview of A Warning and highlighted that Trump had repeatedly discussed doing away with judges.

The author writes, “‘Can we just get rid of the judges? Let’s get rid of the f—ing judges,’ Trump fumed one morning. ‘There shouldn’t be any at all, really.’”

Courts have posed a barrier to many of his policy ideas, including banning Muslim immigrants.

Another excerpt from the book claims Trump “went a step further and asked his legal team to draft up a bill and send it to Congress to reduce the number of federal judges,” but “[s]taff ignored the outburst and the wacky request.”

The preview also shows Trump ignoring Congress’ powers after a leader of a national security agency asked him to support an upcoming defense bill.

“‘Don’t worry about Congress,’ the president said. ‘Just do what you need to do,'” Anonymous wrote, adding that Trump reportedly said, “You have my permission to do whatever you need to do, okay? Just forget about them.”

The White House has not commented specifically about the claim that Trump wants to get rid of judges, but has called the book “nothing but lies.”

“The coward who wrote this book didn’t put their name on it because it is nothing but lies. Real authors reach out to their subjects to get things fact checked — but this person is in hiding, making that very basic part of being a real writer impossible,” the White House said in a statement to Axios.

A Warning will go on sale Nov. 19.

In his tenure as president, Trump has left a significant imprint on U.S. courts.

The Trump administration has appointed nearly 1 in 4 of the nation’s federal appeals court judges and 1 in 7 of its district court judges.
