Three top House GOP leaders donated to their party’s most prominent openly gay House candidate, former San Diego Councilman Carl DeMaio, a top prospect in a competitive California race.

Majority Leader Eric Cantor of Virginia, Majority Whip Kevin McCarthy of California and former Republican Study Committee Chairman Tom Price of Georgia gave campaign cash to DeMaio in June.

“I’m grateful to receive this strong early support, which I believe reflects both my record of getting fiscal reforms done in San Diego and my more inclusive vision for the future as a new generation Republican,” DeMaio said in a Tuesday news release.

Cantor donated $10,000 from his leadership PAC, the maximum donation allowed under campaign finance rules. Price contributed $1,000 from his leadership PAC, and McCarthy gave $5,000 from his leadership PAC.

McCarthy also will host a July 17 fundraiser for DeMaio at the Capitol Hill Club in Washington, D.C.

None of these three Republicans support same-sex marriage. After the Supreme Court struck down the Defense of Marriage Act, Cantor said he was “disappointed in this decision.”
