A controversial dark money group recently created to promote Democratic policies and officials has refused to disclose the location of a secretive donor meeting it will hold in Washington, D.C., next week.

Organizing for Action (OFA), a 501(c)(4) advocacy group created by President Barack Obama’s former campaign manager, will hold an event called the “founders summit” in a Washington hotel on Wednesday, March 13, according to an NPR report.

According to the New York Times, donors will pay $50,000 to attend the event, where they can brush shoulders with OFA chair Jim Messina and Jon Carson, the group’s executive director and the former director of the White House Office of Public Engagement.

For $500,000, donors will enjoy a spot on OFA’s national advisory board, which gives them direct access to the president and other top administration officials. Government watchdog groups have blasted the scheme as a transparent pay-to-play arrangement.

Organizing for Action staff have ignored or rebuffed numerous requests for additional information about the founders summit.

Staff at the organization’s downtown Washington, D.C., office would not answer questions about the event. Multiple attempts to reach OFA spokesperson Katie Hogan at a phone number provided by office staff were unsuccessful. Hogan also did not reply to multiple emails.

Their refusal to disclose information on the event coincided with attempts by OFA to reassure critics that the organization will be transparent and ethical. Messina has rejected claims it will allow wealthy individuals to influence administration policy.
