Sen. Dianne Feinstein (D-CA) knocked her colleague Sen. Rand Paul (R-KY) on Thursday night for warning of hyperbolic scenarios during his 13-hour filibuster.

"No drone is going to be used in the United States against an American citizen walking down a street or sitting in a cafe and, you know, and then there was a stupid example of a drone being used against Jane Fonda," Feinstein remarked on MSNBC. "I mean, I don't think this is befitting the Senate floor."

Paul began the filibuster on Wednesday morning to demand the Obama administration answer whether it believed it was legal under any circumstance to use a drone strike against an American on U.S. soil.

Feinstein said Paul "hyped up" the situation and that his questions were already "cleared up" by the time he started the filibuster. She noted that Attorney General Eric Holder told Sen. Ted Cruz (R-TX) that the government could not kill an American citizen with a drone strike unless the person was an extraordinary and imminent threat.

Feinstein, the chairman of the Senate Intelligence Committee, has demanded that the Obama administration provide Congress with more details of its drone strike program, which has been deployed against suspected terrorists in Yemen and Pakistan.

Wednesday on MSNBC, she called for the regulation of drones, which she described as "the perfect assassination weapon" and also a major privacy concern.

“This question has to be addressed and we need rules of operation on the border, by police, by commercial use and also by military and intelligence use. So this is now a work in progress,” Feinstein said. “The administration is looking at a rules playbook as to how these won’t be used and how they will be used. So It’s a very complicated subject of new technology and I think we have to take a pause and get it right.”
