BATON ROUGE, La. (AP) — U.S. Rep. Charles Boustany has become the third member of Louisiana's congressional delegation to say he opposes U.S. military intervention in Syria.

Boustany, a Republican from Lafayette, announced his decision Monday to vote against President Barack Obama's proposal after a closed-door briefing with other members of Congress, Vice President Joe Biden and senior Obama administration officials.

Boustany says the use of chemical weapons in Syria was deplorable. But he says Obama's proposal to use a military strike doesn't contain a broader diplomatic strategy and will fail to get a political settlement accomplished in Syria.

The Lafayette congressman joins Sen. David Vitter and Rep. John Fleming in Louisiana's delegation in announcing he will vote against the president's request for military intervention against the regime of Syrian President Bashar Assad.
