Ben Sasse resigned from the Senate on Sunday as he prepares to become the president of the University of Florida.

The senator submitted his resignation last month, two years into his second term.

The body that he had been a member of since 2015, the one that he criticized last week, doesn't work very well.

He said that the lives of people living in a politicized echo chamber are not worthy of a place that calls itself a deliberative body.

A big chunk of the performative yelling that happens here and in every hearing room is just about being booked for even more performative when we are being honest with each other.

The seat will be filled by an appointment by the governor of Nebraska. Republican Pete Ricketts was the previous governor.

As a senator, he supported repeal of theAffordable Care Act and voiced opposition to same-sex marriage, but did not vote on the landmark legislation codifying gay marriage rights. He was an assistant secretary in the Bush administration and was elected to the Senate.

He was expected to take the job at the University of Florida, according to NBC. The Board of Trustees approved the next president despite opposition from some faculty and students.

He aired grievances with Trump and his supporters. When Trump ran for re-election in 2020, he was rebuked by Sasse, who said he kissed dictators' butt, flirted with white supremacists, insulted women, and treated the presidency like a business opportunity.

Seven Republicans voted to impeach Trump again after the Capitol attack. He blamed Trump for making false allegations of widespread election fraud in the 2020 election.

The life of the vice president was at risk as a result of those lies. The actions are in violation of the oath of office.
