Two hundred House Republicans, accounting for nearly the entire caucus, signed on to a pledge to oppose a budget bill that eliminates the Hyde Amendment, the measure that prevents federal funding from being used on abortion services.

“We cannot allow the Hyde Amendment and other important pro-life safeguards to be decimated by Congressional Democrats. Accordingly, we pledge to vote against any government funding bill that eliminates or weakens the Hyde Amendment or other current-law, pro-life appropriations provisions,” read the letter to House and Senate leadership, released by the Republican Study Committee.
