John McCain Doesn't Understand Threats to Filibuster Gun Control Legislation

Some of his GOP colleagues are reportedly considering using the tactic

(CNN) - Sen. John McCain said Sunday that he opposes the thought of filibustering a debate over gun legislation that will probably be brought to the Senate floor this week, despite threats of such action by fellow Republican senators.

"I don't understand it. The purpose of the United States Senate is to debate and to vote and to let the people know where we stand," Arizona's McCain said on CBS' "Face the Nation."
