Marijuana activists will write checks to a Republican congressman’s re-election campaign during a Tuesday soiree in the Adams Morgan neighborhood of Washington, D.C.

California Rep. Dana Rohrabacher is the guest of honor at the $250-per-person event, which is also a housewarming party for the Marijuana Policy Project. The organization recently relocated to the night life hot spot from a staid Capitol Hill block it shared with the Heritage Foundation.

“I'm pleased to announce that the housewarming party for MPP's new office in DC will be from 7:00 to 9:00 p.m. on Tuesday, March 11,” MPP Executive Director Rob Kampia said in an emailed event invitation. “Our Republican leader in Congress, U.S. Rep. Dana Rohrabacher (R-Calif.), will be joining us. As such, this housewarming party will serve as a fundraising event for his reelection campaign.”

Attendees can make their donation to the Committee to Re-Elect Congressman Rohrabacher via credit card, with a check or in cash. MPP members pay a discounted $100 (membership costs $25). Donations from corporations and foreign citizens won’t be accepted.

“Beer, wine, and finger food will be served. If the weather is nice, we'll hold the reception on the building's roof deck. If not, the reception will be in MPP's conference room and surrounding hallways,” Kampia said.

The 13-term Orange County Republican is an advocate of relaxing federal pot policies. In April he introduced the Respect State Marijuana Laws Act, which would prohibit the federal prosecution of people complying with state medical and recreational marijuana laws. The bill has five Republican and 20 Democratic co-sponsors.

Kampia described the legislation as “the perfect marijuana bill” in his invite.

In 2007 Rohrabacher co-sponsored an unsuccessful amendment that would have blocked the Department of Justice from spending funds to crack down on medical marijuana facilities in states that allow it, and in February Rohrabacher joined 17 Democratic colleagues to call on President Barack Obama to administratively recatergorize marijuana – something Obama’s so far been reluctant to do.

It's unlikely Rohrabacher will face much of a re-election threat. The Cook Political Report rates Rohrabacher's district as "solid Republican," estimating a 7 percentage point GOP advantage. He crushed his 2012 opponent with a 22 percentage point margin of victory.
