Newt Gingrich's call for a Republican reality check on gay marriage has been lauded by gay GOP group Log Cabin Republicans.

Gingrich, the former House Speaker and a leading candidate for the 2012 GOP presidential nomination, told The Huffington Post on Thursday that he's prepared to accept “a legal document issued by the state” for gay and lesbian couples.

Gingrich added that momentum is on the side of supporters and that he fears the issue could hurt the Republican Party, whose official platform opposes the legalization of marriage equality.

R. Clarke Cooper, executive director of Log Cabin Republicans, lauded Gingrich's change of heart on the issue.

“Log Cabin Republicans welcome former Speaker Newt Gingrich's remarks calling for a Republican reality check on marriage,” Cooper said in a statement. “Gingrich speaks for many Republicans who are concerned about our party's future, and who are ready to accept the freedom to marry matters to many Americans, gay and straight. As Gingrich noted, LGBT people are part of every family and every community, and the time has come for greater inclusion. It is particularly important and welcome to hear that Gingrich now understands the difference between church ceremonies and a civil marriage license, and that equality is no threat to religious freedom.”
