Sen. Dianne Feinstein says she laughed off former Montana Gov. Brian Schweitzer's offensive remarks earlier this week, chalking them up to his "large mouth."

In an interview with National Journal, Schweitzer used a crude analogy to describe Feinstein's relationship with the intelligence community. “She was the woman who was standing under the streetlight with her dress pulled all the way up over her knees," Schweitzer said, "and now she says, ‘I'm a nun,' when it comes to this spying!"

Speaking Sunday on CNN's "State of the Union," Feinstein, D-Calif., said she didn't take Schweitzer's remark too seriously.

"Well, my first reaction was that I laughed, to tell you the truth," Feinstein said. "He clearly has a rather large mouth, and all sorts of things come out. I think that's really too bad, but it's the way it is."

Schweitzer apologized for his comments in a Facebook post this week. But, asked whether Schweitzer has called to personally apologize, Feinstein responded, "No."

"But it says something, doesn't it?" Feinstein added.

Schweitzer, a Democrat, has indicated he would vie for his party's nomination to run for president in 2016, although he is not considered a serious potential candidate by most Democrats.
