Republican U.S. Rep. Tim Griffin says he's opposed to military action in Syria.
The two-term congressman from central Arkansas announced Tuesday he won't support action against Syria, which U.S. officials say killed more than 1,400 civilians in a chemical weapons attack last month.
Griffin, who had already said he was unlikely to support President Barack Obama's request, said a classified briefing he attended Monday had not changed his mind.
Griffin said he believed Obama had not clearly articulated why an attack would be in the nation's interest, the goal or how to handle the aftermath.
Republican Rep. Tom Cotton is the only member of the state's congressional delegation to support military action. The rest have said they oppose or will likely oppose the request.
