Last week, the Courage Campaign noted that Klobuchar was one of two Democratic senators who hadn't signed on to the DOMA repeal bill (the other is Wisconsin's Herb Kohl) and that her office stated that she had not taken a position on the bill. That prompted OutFront Minnesota, the state's largest LGBT advocacy group, to initiate a campaign urging constituents to call on her to support the repeal.

On Tuesday, state Sen. Dibble of Minneapolis noted that he spoke with Klobuchar's staff, who indicated she would vote for the measure.
