“It's a long time until November,” McConnell said when asked about poll numbers that show a majority of Americans don’t think Trump is qualified to be president.

“And the burden, obviously, will be on him to convince people that he can handle this job,” he added.

McConnell said recent changes to the Trump campaign are a “good step in the right direction.”

“He's beginning to use a prepared script more often, which I think is absolutely appropriate for any candidate, whether you're a longtime politician like [presumptive Democratic presidential nominee] Hillary Clinton Hillary Diane Rodham ClintonJeff Flake: Republicans 'should hold the same position' on SCOTUS vacancy as 2016 Momentum growing among Republicans for Supreme Court vote before Election Day Warning signs flash for Lindsey Graham in South Carolina MORE or whether you're new to the game like Donald Trump,” he added.

When pressed on whether he thinks Trump is qualified, McConnell said he will “leave that to the American people to decide.”

“You know, he won the Republican nomination fair and square. He got more votes than anybody else against a whole lot of well-qualified candidates. And so our primary voters have made their decision as to who they want to be the nominee,” he said.

“The American people will be able to make that decision in the fall.”
