Sen. Paul suggests filibuster 'round 2' coming

A week earlier Paul held a roughly 13-hour filibuster on John Brennan's nomination to lead the CIA. Paul filibustered Brennan's nomination in order to push the Obama administration to respond to Paul's questions about drone policy.

A number of Republicans joined Paul's filibuster and Senate Minority Leader Mitch McConnell (R-Ky.) praised him for it.

McConnell has also highlighted support for the filibuster in a campaign email.
