Former Attorney General William Barr said Friday that former President Trump's presidency would be a "horror show" if he were re-elected because his former boss lacks the "discipline" as well as the "ability for strategic thinking" needed to get things done.

"It is a horror show, you know, when… he's left to his own devices," Barr said in remarks at the City Club of Cleveland on Friday in Ohio.

"If you believe in his policies, what he's advertising is his policies, he's the last person who could actually execute them and achieve them," Barr said to a reporter who asked if Trump is fit to be president again.

The reporter noted that some voters say they want Trump re-elected for his policies, and are willing to overlook his mistakes as president in his last term.

"He does not have the discipline," Barr replied. "He does not have the ability for strategic thinking and linear thinking or setting priorities or how to get things done in the system."

"And, and so you may want his policies. But Trump will not deliver Trump policies," Barr said.

"He will deliver chaos, and if anything lead to a backlash that will set his policies much further back than they otherwise would be," Barr said.
