Sen. Rand Paul (R-Ky.), one of the most outspoken opponents of military action in Syria, wouldn't rule out the possibility Tuesday of launching a standing filibuster over the issue in the Senate.
"I can't imagine that we won't require 60 votes on this," Paul told reporters on an afternoon conference call. "Whether there's an actual standing filibuster -- I've got to check my shoes and check my ability to hold my water. And we will see. I haven't made a decision on that."
