When it comes to scandals prompting congressional resignations, departures from the U.S. House happen with relative frequency. We saw one in October, for example, and it didn't cause much of a fuss.
U.S. senators, however, resign from Congress under a cloud of scandal far less frequently. In the last 20 years, plenty of senators have left before the end of their terms to take other jobs or due to illness, but only one -- Republican John Ensign of Nevada -- was forced out by a controversy.
Today, however, there was another.
Sen. Al Franken, D-Minn., the former "Saturday Night Live" comic who made an improbable journey to become a leading liberal voice in the Senate, announced on Thursday that he will leave office in the coming weeks, after a string of allegations of sexual misconduct and mounting pressure from Democratic lawmakers to step down.
"Today I am announcing that in the coming weeks, I will be resigning as a member of the United States Senate," Franken said during an emotional speech from the Senate floor.
It's not yet clear exactly when Franken will formally leave Capitol Hill, but he'll reportedly give up his seat at the end of the month. It means he's likely to remain in the chamber for the final vote on the Republican tax plan, which is expected before Christmas.
The Minnesotan seemed to make today's announcement grudgingly, arguing in his remarks, "Some of the allegations against me simply are not true, others I remember very differently." Franken conceded, however, that the scandal would make it impossible for him to be an effective lawmaker.
"[T]his decision is not about me. It's about the people of Minnesota," he said. "It's become clear that I can't both pursue the Ethics Committee process and at the same time, remain an effective senator for them."
Of course, there's the broader political landscape to consider, and Franken took the opportunity to highlight the details intended to make Republicans uncomfortable.
