Massachusetts Congressman Barney Frank opposes openly gay GOP congressional hopeful Richard Tisei.

Tisei is running to represent the people of Massachusetts' Sixth District.

The 49-year-old Tisei announced in a 2009 Boston Globe interview before he was named Charlie Baker's gubernatorial running mate that he is gay. Baker was defeated by Democrat Deval Patrick.

If elected, Tisei, a former Massachusetts state senator, would become the nation's first openly gay Republican Congressman.

“The fact that Richard Tisei is openly gay is a good thing,” Frank said Thursday in a conference call with reporters. “The problem is that is of no use to us.”

Frank explained that Tisei's first vote would be to keep Ohio Rep. John Boehner as House Speaker. Boehner opposes efforts to repeal the Defense of Marriage Act (DOMA).

Tisei supports repeal, but Frank said that was not relevant.

“If he is helping them keep the majority that is irrelevant because the bill will not come up,” the Boston Herald quoted Frank as saying.

Tisei has the backing of Boehner, who attended a fundraiser which took place at the Taj Boston hotel in June. Three candidates benefited from Boehner's appearance: Tisei, and Representatives Charles Bass and Frank Guinta of New Hampshire.

Frank is backing the reelection of fellow Democrat John Tierney.
