Senate Minority Leader Mitch McConnell said Sunday that it was "premature" to predict whether Republicans would filibuster the confirmation of Supreme Court nominee Elena Kagan. "I think it's entirely too early to determine whether this nominee would be subjected to a 60-vote threshold," the Kentucky Republican said on "Fox News Sunday," later adding, "I have never filibustered a Supreme Court nominee, but it is possible but entirely too early to know whether that would be appropriate." Earlier this year, McConnell struck a different note while on Fox, saying that a filibuster would be "highly unlikely." In recent weeks, however, he has criticized Kagan for saying in 2009 that she thought the prohibition of some political pamphlets could be allowed. Kagan is currently the solicitor general. "I think some of her views are quite troubling — at least to me — in the area of political speech and the First Amendment," McConnell said.
