Democrats are set to include a pro-gay marriage plank in their convention platform for the first time in history, party sources confirm to POLITICO. The language was approved unanimously by a 15-member platform draft committee, and now heads for approval by the full platform committee in August.

The party’s Platform Drafting Committee agreed, unanimously, to approve the language at a meeting this weekend in Minneapolis.
A source in the meeting said the decision was “not controversial.”

The language will not become official until the party’s full Platform Committee meets Aug. 10 in Detroit.

The effort to include gay marriage in the platform gained increased momentum after President Barack Obama announced in May that his views on the issue had changed to support legalization.
