Colorado Common Cause

Bird did not attend the retreat and had resigned as the chair of the Opportunity Caucus, which hosted the gathering, in August.

The Opportunity Caucus lawmakers face allegations they violated the state’s gift ban by attending a Vail retreat with lobbyists paid for by dark money.

The complaints were filed by Colorado Common Cause, a liberal-leaning nonprofit that advocates for an open government. They were submitted to Colorado’s Independent Ethics Commission, which is charged with reviewing allegations of violations of the state’s 20-year-old gift ban.
