Former U.S. Attorney General William Barr said in an interview that aired Friday on PBS that his former boss, Donald Trump, should “stand aside” and forego his campaign for another presidential term because he doesn’t have what it takes.

Barr also said it appeared “increasingly more likely” that the Department of Justice will indict Trump for the hoard of classified documents from the White House that the FBI found stashed at his Mar-a-Lago resort in Florida. And the Justice Department “probably” has what it needs for “legitimately indicting” him, Barr added.

As for another run at the presidency, Trump “failed” the first time, Barr told news host Margaret Hoover in the interview on “Firing Line.”

“He didn’t do what the whole country hoped — that he would rise to the occasion and rise to the office, and he didn’t do that,” said Barr.

“So he’s had his chance,” Barr said. “He obviously does not have the qualities necessary to unite the party, which is the first step on the road back, and he should stand aside.”
