ATLANTA (AP) – A chief supporter of legislation shielding same-sex marriage opponents says he will discuss the possibility of a special session with colleagues.

Georgia’s General Assembly has left the Capitol for the year, adjourning after midnight on Thursday. Lawmakers can ask the governor to convene a special session, but need a three-fifths majority in both the House and Senate.

Overriding a governor’s veto requires a two-thirds vote in each chamber. Republicans don’t hold that margin in either the House or Senate, and all Democrats voted against the bill. Several Republicans in the Senate and one in the House also voted no.

Representatives for House Speaker David Ralston and Lieutenant Governor Casey Cagle didn’t immediately respond to emails seeking comment.

Sen. Josh McKoon, a Columbus Republican, says he was disappointed by Deal’s decision.
