(CNN) - Senate Minority Leader Mitch McConnell told CNN Sunday he disagrees with conservative commentators who have labeled Supreme Court nominee Sonia Sotomayor a racist, but said he has better things to do than be "the speech police."
"Look. I've got a big job to do dealing with 40 Senate Republicans and trying to advance the nation's agenda, and better things to do than be the speech police over people who have their views about a very important appointment," McConnell told CNN's John King on State of The Union. "So I'm not going to get into policing everybody's speech."
The comments come two days after Texas Sen. John Cornyn, the chairman of the National Republican Senatorial Committee, publicly repudiated recent statements from conservative commentators Rush Limbaugh and Newt Gingrich calling Obama's choice for the high court a "racist."
"I think it's terrible," Cornyn told NPR Thursday. "This is not the kind of tone any of us want to set when it comes to performing our constitutional responsibilities of advise and consent.”
McConnell told King Sunday the idea that Sotomayor is a racist - a notion largely based on her 2001 speech at Berkeley - is "certainly not my view."
"My view is we ought to take a look at this nominee's qualifications,” McConnell said. “I think her life story is absolutely impressive."
But the Senate Minority Leader added he would not rule out pushing for a filibuster against Sotomayor after a thorough investigation into her past rulings and statements.
"To predict [a filibuster] in the same week that the nominee is put forward is putting the cart before the horse," McConnell said. "We have no earthly idea whether that would be appropriate at some point in the process. We've got a lot of cases to read and a lot of background to check."
