Republican Alabama Governor Robert Bentley argues in an amicus brief filed with the Supreme Court that gay couples marrying harms children.

The nation's highest court will hear oral arguments in a case challenging marriage bans in Ohio, Kentucky, Michigan and Tennessee on April 28, with a ruling expected in June.

Bentley's lawyers urged the Supreme Court to uphold such bans, arguing that allowing gay couples to marry destroys the “rights of children to be connected to their biological parents.”

U.S. District Judge Callie “Ginny” Granade dismissed similar arguments made by the state in a case that declared the state's restrictive marriage ban unconstitutional.

The Alabama Supreme Court on March 3 temporarily restored the ban when it ordered probate judges to stop issuing marriage licenses to gay and lesbian couples.

Plaintiffs responded by filing a class action lawsuit.
