WASHINGTON- Minnesota Sen. Al Franken is resigning amid multiple sexual misconduct allegations.

Once a rising star in the Democratic Party, Franken made the announcement in a speech Thursday on the Senate floor.

Sen. Al Franken: "There is some irony in the fact that I am leaving while a man who has bragged on tape about his history of sexual assault sits in the Oval Office." https://t.co/HgnJl4IPml pic.twitter.com/zSfxqKtgEo

The two-term lawmaker has repeatedly apologized as several women stepped forward to accuse him of sexually inappropriate behavior, from groping to forcibly trying to kiss them.

But a fresh allegation on Wednesday unleashed a torrent of Democratic demands that Franken step aside. Female senators led the chorus.

Franken is an actor who appeared on "Saturday Night Live" and an author who narrowly won his Senate seat in 2008 after a prolonged vote count. He has been a fierce opponent of the Trump administration.

His political fall has been swift by congressional standards. The first allegation surfaced on Nov. 16.
