U.S. Sen. Jon Tester says that he opposes a military strike in Syria.
The Obama administration had asked Congress to vote for military action against Syria to destroy its chemical weapons.
In recent days, though, focus has shifted to diplomatic efforts where Syria possibly could turn over its stockpile.
Tester said Thursday in a statement that he has been listening to Montanans and is "convinced a military strike at this time will only make the situation worse." The Democrat says the best solution is pressuring Syria to give up its chemical weapons.
Earlier this week, Republican U.S. Rep. Steve Daines said he would oppose military action in Syria.
U.S. Sen. Max Baucus has said it's unclear if a vote will even be requested.
