"I don't know, because I hear him saying a lot of different things," McCain says of Trump appointing justices.

McCain added that the Senate would oppose any Supreme Court nominee Hillary Clinton puts up.

CNN  — 

Republican Sen. John McCain said on Monday that he wasn’t sure if Donald Trump would be a better president for appointing Supreme Court justices than Hillary Clinton.

Trump has released lists of 21 potential justices. He has pledged to choose from among those 21 when making Supreme Court selections, in a move that has earned him praise from conservatives, including his former rival in the Republican primary, Texas Sen. Ted Cruz.

Asked on the Dom Giordano program on 1210 WPHT Philadelphia radio whether Trump was the superior candidate on issues like the Supreme Court, the Arizona senator replied, “Uh, first of all, I don’t know, because I hear him saying a lot of different things.”

Later in the interview, McCain used the opportunity to make the case for fellow Republican Sen. Pat Toomey, who is locked in a close battle to retain his Senate seat in Pennsylvania. McCain promised that Republicans would be “united against any Supreme Court nominee” put forth by Clinton.

“I promise you that we will be united against any Supreme Court nominee that Hillary Clinton, if she were president, would put up,” McCain said. “I promise you. This is where we need the majority and Pat Toomey is probably as articulate and effective on the floor of the Senate as anyone I have encountered.”

A spokesperson from McCain’s Senate office later clarified his comments on opposing a Clinton-nominated justice.

“Senator McCain believes you can only judge people by their record and Hillary Clinton has a clear record of supporting liberal judicial nominees,” said McCain spokesperson Rachael Dean. “That being said, Senator McCain will, of course, thoroughly examine the record of any Supreme Court nominee put before the Senate and vote for or against that individual based on their qualifications as he has done throughout his career.”

Asked in the radio interview about the decision to un-endorse his party’s nominee the day after a 2005 audiotape leaked to the Washington Post wherein Trump could be heard describing how he forces himself on women, McCain said, “It’s not what he said, my friend, it’s what he said he did.”

“What he said he did,” he continued. “I mean, bragging is one thing. I’ve been in a lot of locker rooms, my friend, and frankly I have not heard comments like that.”
