One House Member of Portuguese ancestry was expelled from the House in December 2023, and an additional Hispanic House Member was sworn in in July 2024.
27 One Hispanic Senator resigned in August 2024.

Military Service
At the beginning of the 118th Congress, there were 98 individuals (18.1% of the total membership) who had served or were serving in the military, 7 more than at the beginning of the 117th Congress (91 Members). According to lists compiled by CQ, the House as of January 2023 had 82 veterans (including 5 female Members, as well as 2 Delegates); the Senate had 16 veterans, including 2 women.33 These Members’ service included tours of duty in the Vietnam War and the Persian Gulf War, and combat or peacekeeping missions in Afghanistan, Iraq, and Kosovo. As of August 2024, three House Members are still serving in the Reserves, and four House Members are still serving in the National Guard. Four of the seven female veterans are combat veterans.
The increased number of veterans in the 118th Congress reverses the trend of steady decline in recent decades in the number of Members who have served in the military. For example, 64% of the Members of the 97th Congress (1981-1982) were veterans, and in the 92nd Congress (1971- 1972), 73% of the Members were veterans.34
