Former Attorney General Bill Barr said Friday that former President Donald 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 in Ohio on Friday.

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