Rep. John Conyers (D-MI) announced he is retiring after allegations of sexual misconduct on Tuesday. The Hill's Niv Elis explains the significance of this move in Washington.

Elis said this is a "really big deal," and wonders Conyers' announcement marks an incremental shift towards a zero-tolerance approach on Capitol Hill. Several women have come forward with allegations of sexual misconduct against the congressman. More claims surfaced after BuzzFeed News reported on a 2015 settlement regarding a wrongful dismissal complaint. Conyers has denied accusations of sexual misconduct.

"Stepping down because of allegations is a sign of shift in what and how Washington is dealing with sexual misconduct issues," said Elis. On Tuesday, Conyers said he is endorsing his son for his seat in Congress.
