Sources familiar with deliberations within the caucus said women Democratic senators pressed their leadership to resolve the Franken situation and the leaders relayed their concerns to him.   

“There were conversations by a number of senators who were concerned about the allegations and believed the women,” said one Democratic senator.

The drive to oust Franken was led by the women of the Senate, who felt it was a defining moment in national politics. They worried that if Franken were allowed to stay in the Senate despite a steady stream of harassment allegations, they would look weak or even hypocritical.

At first, Franken’s Democratic colleagues were OK with letting him stay in the chamber while the Senate Ethics Committee investigated the charges against him.

But as more accusers came forward and the allegations piled up, women senators grew concerned that the Ethics Committee would not move quickly or decisively enough to spare the Senate and the Democratic Party lasting political damage.

Even though Franken’s colleagues didn’t think the allegations about his past behavior were equivalent to allegations facing Moore, who is accused of sexual misconduct with teenagers, they feared that voters might not see much difference.

When Franken finally announced his plans to leave Congress in an emotional speech Thursday morning, it came as a relief to many of his Democratic colleagues.

Afterward, more than 20 colleagues lined up on the Senate floor to hug him or shake his hand. Not one, however, delivered any remarks in praise or recognition of his Senate accomplishments.

Franken refused to admit any misconduct in a defiant floor speech announcing his decision to leave.

A spokesman for Franken did not respond to a request for comment.

The defiance reflected Franken’s desire to hang on to his position in the Senate.

He claimed the allegation was “categorically not true” and waved off elements of the woman’s story as “preposterous,” according to a statement to Politico. 

Schumer held a second meeting with Franken and his wife, Franni, at Schumer’s apartment in Washington, D.C., early Wednesday afternoon and again argued that he should step down.

By this time, a fast-growing number Democratic senators had issued public statements calling on Franken to leave the Senate.

While acknowledging that Franken had a right to wait for the results of the ethics investigation, she said “it would be better for our country if he sent a clear message” that harassment isn’t acceptable by stepping aside.

By the end of the day Wednesday, a total of 33 Democratic senators had called for Franken’s ouster, more than half the caucus.

Schumer, who had been close to Franken, delivered the final blow. 

Although the leader acknowledged Franken was “a dear friend,” Schumer said his colleague had “a higher obligation to his constituents and the Senate.”

The desire to send a signal different than the one sent by Republicans backing President Trump played a part in the opposition to Franken.

The election of Trump after a recording of him making lewd comments about grabbing women became public has since galvanized the Democratic base — especially women — and Democratic senators say they have to pay attention to this powerful political force.

“We’re in the middle of a big cultural shift and I think particularly young women are not going to stand for this kind of behavior and, most importantly, the intimidation that comes with it,” said Sen.

Feinstein said Trump’s comments about women on the Access Hollywood tape “really brought it to the fore.”

“To hear a man say those things and become president of the United States and all of his accusers are kind of banished to nowhere almost subconsciously in women has had a big effect,” she added.
