WASHINGTON (AP) - The GOP has split over a Republican senator's filibuster of President Barack Obama's CIA nominee and claims about the use of drones in the Unites States.

Kentucky Sen. Rand Paul spoke for nearly 13 hours on Wednesday, demanding an answer from the administration on its authority to use lethal force and drones.

But Republicans John McCain and Lindsey Graham said Thursday that Paul's claims were unfounded, and said the debate unnecessarily created fear among Americans.

Graham says Obama's actions were similar to what Republican President George W. Bush did.

McCain scoffs at Paul's suggestion that the U.S. would have attacked Jane Fonda when she traveled to North Vietnam during the war.
