Mitch McConnell has some advice for Donald Trump

Senate Majority Leader Mitch McConnell offered some advice Monday for the presumptive GOP presidential nominee.

In an interview on "CBS This Morning," the Kentucky Republican was asked what he would like to see Donald Trump do differently as the 2016 race shifts toward the general election.

"I'd like to see a more studious approach," said McConnell, who suggested that Trump should use prepared texts more to deliver speeches instead of delivering them off-the-cuff.

"I think that winning the White House is about more than just entertaining a large audience," he added. "I think the American people would also like to see him fill in the blanks."

Trump's list of potential Supreme Court nominees, McConnell said, was "excellent" and "well-thought out and reassuring."

McConnell explained that he endorsed Trump because he says Hillary Clinton would mean four more years of President Obama's policies.

"The country is yearning for a change," he said. "I'd rather take my chances on somebody new, particularly with regard to the Supreme Court."

McConnell said that the GOP is uniting despite the fact that House Speaker Paul Ryan, R-Wisconsin, has not yet endorsed Trump and a number of top Republicans like Mitt Romney and John McCain plan to skip the Republican National Convention in Cleveland this July.

At the same time, McConnell admitted that both Clinton and Trump are unpopular.

"Neither one of these candidates is likely to get a big wet kiss from the American public," he said.
