6 GOP House members opposed a bill meant to document and preserve evidence of war crimes during Russia's invasion of Ukraine

• Seven House Republicans voted against a bill meant to preserve evidence of war crimes by Russia.
• Rep. Liz Cheney was among them, but a spokesperson said it was a mistake and she would amend it.

Six Republican lawmakers in the House opposed a bill passed Wednesday seeking to encourage efforts to document and preserve evidence of Russian war crimes during the war in Ukraine.

The bill, introduced in the House on March 29 and sponsored by GOP Rep. Michael McCaul of Texas, seeks to "direct the President to submit to Congress a report on United States Government efforts to collect, analyze, and preserve evidence and information related to war crimes and any other atrocities committed during the full-scale Russian invasion of Ukraine since February 24, 2022."

The bill, titled the Ukraine Invasion War Crimes Deterrence and Accountability Act, asserts that Russian forces have intentionally attacked civilians and nonmilitary buildings, engaged in unnecessary wanton destruction of property, and unlawfully deported civilians and taken hostages.

There were 418 yes votes and four lawmakers who abstained. Seven Republicans — Reps. Tom Massie of Kentucky, Scott Perry of Pennsylvania, Marjorie Taylor Greene of Georgia, Warren Davidson of Ohio, Liz Cheney of Wyoming, and Andy Biggs and Paul Gosar of Arizona — voted against the bill.

A spokesperson for Cheney, however, told The Hill that Cheney's nay vote was a mistake and that she would inform the House clerk that she meant to vote in approval of the bill.

Having passed Wednesday, the bill will proceed to the Senate for a vote.

Massie, Perry, Greene, Davidson, Biggs, Gosar, and Cheney didn't immediately respond to requests for comment.
