Former Georgia Congressman Bob Barr, who authored the Defense of Marriage Act but has since come out in favor of its repeal, will be keynote speaker at Log Cabin Republicans' National Convention in Dallas next month, according to a press release from the group.

The convention is set for April 28 through May 1 at the Hilton Anatole Hotel, and Barr will speak at the National Dinner on April 30.

"Congressman Barr is living proof that Republicans are becoming more inclusive, and doing so for conservative reasons," said R. Clarke Cooper, Log Cabin Republicans Executive Director, in a press release.
