Since GOP Congress members (who are in the minority) can't force a vote in Congress to overturn the DC same-sex marriage question, they have filed an amicus brief in D.C. Superior Court calling for a public referendum on the issue.

In The Washington Post's "DC Wire" section
Thirty-nine congressional Republicans, including House Minority Leader John Boehner (Ohio) and Minority Whip Eric Cantor (Va.), have filed an amicus brief in D.C. Superior Court calling for a voter referendum on whether to legalize same-sex marriage in the District.
In the filing, U.S. senators James Inhofe (Okla.) and Roger Wicker (Miss.) and 37 House Republicans align with Bishop Harry Jackson, pastor of Hope Christian Church, in asking the court to reverse a D.C. Board of Elections and Ethics decision prohibiting the same-sex marriage question to be put before voters.
