Senate Majority Leader Mitch McConnell
and Texas Senator Ted Cruz are among the 57 congressional Republicans
calling on the Supreme Court to uphold gay marriage bans.
The nation's highest court will hear
oral arguments in a case challenging bans in four states on April 28,
with a ruling expected in June.
In a brief filed at the Supreme Court
on Friday, the GOP lawmakers argue that voters and their elected
legislatures should decide the issue, not judges, the AP
reported.
Cruz, who is running for the 2016
Republican presidential nomination, is an outspoken opponent of
marriage equality. At a campaign stop this week in Iowa, he called
for prayer in support of such bans.

Last month, 218 members of Congress,
including 7 Republicans, called on the justices to strike down the
bans.
