BATON ROUGE, La. (AP) — U.S. Rep. Charles Boustany has become the third member of Louisiana'scongressional 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.

“After reading the classified intelligence reports, attending numerous meetings and briefings with senior Administration officials, and consulting with my colleagues in both the House and Senate, I will not support the authorization of the use of military force in Syria," says Boustany.

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.

“For nearly two years, Syria has been engulfed in a complex civil war with terrorist groups on both sides," says Boustany. "The use of chemical weapons by the Assad regime is deplorable. However, the proposed use of military action alone in Syria, in the absence of a broader diplomatic strategy, will fail to achieve the objective of arriving at a political settlement.”

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