U.S. Sen. Al Franken, trying to salvage his political career, said on Sunday he does not plan to resign but called himself "embarrassed and ashamed" by his behavior toward women who have accused him of groping or inappropriately touching them.

Franken, a Democrat and former comedian who has represented Minnesota in the Senate since 2009, said in a round of media interviews — his first since the allegations surfaced on Nov. 16 — that he looked forward to returning to his job on Monday.

"I'm embarrassed and ashamed. I've let a lot of people down and I'm hoping I can make it up to them and gradually regain their trust," Franken told the Minneapolis Star Tribune.
