Bob Menendez is a member of the Democratic Party and is currently serving as a United States Senator from New Jersey. He was first appointed to the U.S. Senate by Governor Jon Corzine in 2006 and has been re-elected to his seat three times since then. Menendez has held several leadership positions in the Senate, including serving as the Chairman of the Senate Foreign Relations Committee from 2013 to 2015 and again from 2021 to 2023.

Despite being indicted on corruption-related offenses, Menendez has not resigned from his position in the Senate and is currently considering running for re-election. While some Democrats have called for him to step down, most in the party are doing little about it other than hoping he goes away. Rep. Andy Kim has announced that he plans to challenge Menendez in the Democratic primary next year should the incumbent run for re-election.

In summary, Bob Menendez is a member of the Democratic Party and is currently serving as a United States Senator from New Jersey.
