Sen. Joe Manchin (D-W.Va.) announced Thursday that he is opposed to the Senate's resolution on using military force in Syria.

"Given the case that has been presented to me, I believe that a military strike against Syria at this time is the wrong course of action," Manchin said in a statement. "In good conscience, I cannot support the Senate Foreign Relations Committee’s resolution and will be working with my colleagues and the administration to develop other options. I believe that we must exhaust all diplomatic options and have a comprehensive plan for international involvement before we act.”

Manchin becomes the 14th senator and third Senate Democrat to oppose the resolution. The other two Democratic opponents — Sens. Tom Udall (D-N.M.) and Chris Murphy (D-Conn.) — voted against it in the Foreign Relations Committee.

The resolution stands a better chance of passing in the House than the Senate, but it only passed out of committee on a 10 to 7 vote, which suggests that it could be susceptible to a filibuster and may need 60 votes.
