Rep. Barney Frank, the first openly gay member of Congress, says he’d rather see gay rights supporters lobbying their elected officials than marching in Washington this weekend, calling the demonstration “a waste of time at best.”

Frank , in an interview with The Associated Press, said he considers such demonstrations to be “an emotional release” that does little to pressure Congress.

“The only thing they’re going to be putting pressure on is the grass,” the Massachusetts Democrat said Friday…

“Call or write your representative or senator, and then have your friends call and write their representative or senator,” Frank said. “That’s what the NRA does. That’s what the AARP does.”
