Senator Johnny Isakson dealt a blow to supporters of military action in Syria Monday, formally declaring himself a “no” in the coming vote on a resolution authorizing military action.

“After carefully weighing this very important issue, I have decided that I will vote against the resolution to authorize a U.S. military strike in Syria,” read a press release from his office. “Over the past week, I have traveled my state and have talked personally to hundreds of Georgians. Thousands more constituents have contacted my office by phone and email. It is clear to me that Georgians overwhelmingly oppose our country getting involved militarily in Syria.”

The decision follows a Friday report from 11 Alive in which a spokeswoman reported him to be undecided at the time.

Isakson had previously indicated he was open to intervening in Syria, while steadfastly remaining critical of President Obama’s handling of the situation. The late Monday afternoon release struck a similar tone, calling the administration’s approach, or lack thereof, “troubling.”

The decision aligns him the bulk of Georgia’s GOP congressional delegation, which saw Rep. Tom Graves join the likes of Reps. Jack Kingston, Phil Gingrey, Paul Broun, Austin Scott, Rob Woodall, and Lynn Westmoreland as “no” votes today, too.

Senator Saxby Chambliss remains supportive of intervention, though he stated in that same 11 Alive report that he would have to see the final language of any resolution before being firmly in favor.
