The Denver Post: A Denver progressive activist is suing two Democratic state lawmakers and the invite-only caucus they lead, alleging they violated the Colorado Open Records Act.

The lawsuit, filed Friday, is the latest front in the intraparty fight over an October legislative retreat. Derrick Blanton’s suit asks a judge in Denver to order Sen. Lindsey Daugherty and Rep. Sean Camacho to turn over records related to the Colorado Opportunity Caucus and a retreat the group organized in Vail.

According to the lawsuit, Camacho, Daugherty and the Opportunity Caucus — a group of more than two dozen Democratic lawmakers who are generally more moderate on business issues — denied Blanton’s requests for records about the retreat, arguing they had no documents responsive to his request.
