But that's not sufficient for some lawmakers.
Smith and Sen. Mark Udall, D-Colo., have introduced legislation that would repeal the provision on indefinite detention and reverse the mandatory military custody for foreign terrorist suspects linked to al-Qaida or its affiliates and involved in plotting or attacking the United States.
"I will continue to push that bill," Smith said in an interview. "I know the majority is also putting together some ideas. They're very process-focused. ... I have not seen specifics of that proposal yet and we'll talk to them about it, but obviously I have a much stronger position on that and think that we don't need to have indefinite detention or military custody for the people in the U.S."
Amash is determined to change the law, using town halls in his district and the long reach of Facebook to get his message out. He said many Republicans voted for the defense bill in December after they were promised that legislation fixing the provision would be introduced after Christmas. He's still waiting.
"What I've seen from members of Armed Services Committee is basically an attempt to justify the language as it stands," Amash said. "And considering the extent to which they've dug in their heels on this issue, I'd be surprised if they're actually going to make a real and credible change to the language."
