Sen. Al FrankenAlan (Al) Stuart Franken#MeToo era shows there's almost never only one accuser, says Hill.TV's Krystal Ball Hypocrisy in Kavanaugh case enough to set off alarms in DC GOP in striking distance to retake Franken seat MORE (D-Minn.) said in an interview broadcast Sunday that the comedian in him would be hard pressed to mock his record during his first term as a senator in Washington.

“I’ve just been impeccable,” he joked on ABC’s “This Week” during an interview as he campaigned for reelection in rural Minnesota. “I’ve made some small mistakes, I suppose.”

The Minnesota Democrat said he’s been selective in using humor during hearings and on the Senate floor.

“Will I crack wise? Sure,” he said. “That’s who I am.”

“I was always a serious person,” he added.

The senator, who rose to prominence on “Saturday Night Live,” won his Senate election by 312 votes. “I think I felt that I wanted to prove to all Minnesotans that I was going to work for them,” he said of those results.

Franken said he is now “very comfortable” running as a Democrat during President Obama’s second term.

The of rollout ObamaCare was “pretty disastrous,” he said, however, adding that parts of the healthcare reform law need “fixed.”

The senator, who keeps a low profile in Washington and generally avoids the press, has become a visible and vocal force when it comes to merger deals like the one now being proposed by Comcast.

He opposed the company’s 2011 purchase of NBC and is now waging a one-man crusade against Comcast’s proposed merger with Time Warner Cable in hearings, letters and television appearances.
