House Ethics Committee investigating Eric Swalwell

• Multiple House lawmakers have called for Swalwell to either quit Congress or face expulsion.
• The Ethics Committee said it will examine whether Swalwell "engaged in sexual misconduct, including toward an employee working under his supervision."
• Swalwell's office did not immediately respond to Axios' request for comment.

Driving the news: Swalwell has given no indication he plans to step down from Congress despite bipartisan calls to do so.

• Rep. Anna Paulina Luna (R-Fla.) plans to force a vote to expel Swalwell when Congress returns this week.
• Democrats in turn will offer a resolution to expel Rep. Tony Gonzales (R-Texas), who's being investigated by House Ethics over sexual misconduct allegations.

The big picture: Expelling a member of Congress requires a two-thirds majority vote.

• Leadership could move to refer any expulsion resolution to the Ethics Committee instead of having an up or down vote on the resolution.
• Lawmakers have historically been reluctant to expel members before a criminal conviction or the conclusion of an Ethics probe, which could take months or even years.

Zoom in: Democratic support for Swalwell quickly eroded after the San Francisco Chronicle and CNN reported on four women who accused him of sexual misconduct on Friday.

• All 21 of the House and Senate Democrats who had been supporting his campaign rescinded their support, with several Democratic Party leaders calling on him to exit the gubernatorial race.
