Former House Speaker Brent Jones has left his post in the House, the first female speaker to do so in decades.

The news came as a shock to many, and sparked speculation over whether Jones’ departure was a signal of a change in leadership in the Democratic caucus.

The House majority leader’s office confirmed that Jones was resigning on Thursday afternoon.

Jones’ office had not responded to a request for comment.

The Hill had reported on Monday that the Texas Democrat had resigned from the House after an internal investigation into her role in the alleged affair.

Jones had denied wrongdoing and was still a member of the House of Representatives when the alleged misconduct occurred.

Jones’ departure from the minority leader’s position came as Democrats in the caucus were struggling to hold onto power in a midterm election.

The House’s top Democratic leader, Rep. Keith Ellison (D-Minn.), has said he plans to seek a second term, and the Democratic Congressional Campaign Committee (DCCC) had previously said it was “open to supporting the party’s nominee.”
