Rep. Jason Chaffetz (R-Utah) tweeted on Thursday to express his opposition to the passage of the Homeland Security appropriations bill, which allows Guantanamo Bay prisoners to stand trial in the U.S.

The measure was opposed by a broad swatch of Republicans, who claimed that terror trials in the U.S. would pose security concerns and provides undeserving individuals with American legal protections.

He tweeted:

I voted NO on Homeland Security let's GITMO detainees into USA and is a 22% increase in overall appropriations

Chaffetz was one of the first lawmakers to tweet about the vote, which represents a positive step for the Obama administration's effort to close the Gitmo facility by January.

The provision does not allow Gitmo detainees to be transferred to U.S. prisons, en masse. Republicans also opposed that move, arguing it would increase the chances of another terror attack on U.S. soil. Instead, the bill only allows a prisoner who is facing trial to be transferred.
