Rep. David Cicilline of Rhode Island has announced that he is going to challenge longtime Democratic leader Rep. Jim Clyburn of South Carolina for the No. 4 position in House Democratic leadership.

Cicilline’s bid follows the frustrations expressed by many young Democrats who were hoping to see Clyburn leave his position of leadership in the same way that House Speaker Nancy Pelosi and Majority Leader Steny Hoyer have announced that they would be stepping aside in order to allow a new generation of Democratic leaders to emerge.

In a letter to his Democratic colleagues Cicilline, 61, said that he was moved to run for the position following the recent shooting in Colorado Springs at the LGBTQ nightclub Club Q. He added that with such high stakes being in the game, it is incredibly important that those in the House Democratic Leadership team can reflect the diversity of the American people. He added that this is why adding “an LGBTQ+ member at the leadership table,” is important.

The Democrats have already elected new young members of the party in leadership positions with Rep. Hakeem Jeffries, 52, of New York, becoming the new minority leader. Jeffries is the first Black lawmaker to lead either one of the political parties in either chamber. Reps. Katherine Clark, 59, of Massachusetts, and Pete Aguilar, 43, of California, are the other two of the party’s three top leaders.

The Cicilline-Clyburn race is set to be decided on Thursday after a closed-door vote takes place.
