A new analysis by the National Women’s Defense League has revealed dozens of U.S. congressmembers have been accused of sexual misconduct over the past two decades. More than 50 accusations of workplace sexual harassment, largely coming from legislative staff, have been made against at least 30 lawmakers of both parties. The organization also looked at dozens of accusations of sexual harassment outside the workplace against U.S. lawmakers, as well as misconduct on the campaign trail.

This comes after Republican Congressmember Tony Gonzales of Texas and Democratic Congressmember Eric Swalwell of California resigned from Congress earlier this month. Both of them faced potential expulsion votes after they were accused of sexual misconduct.

On Monday, the House Ethics Committee released a statement calling for survivors of sexual misconduct to report their accusations to congressional authorities. Many lawmakers are now calling for the expulsion of Republican Congressman Cory Mills of Florida as he faces an ongoing probe from the House Ethics Committee into allegations of financial misconduct and sexual harassment. Mills has denied the allegations.
