The pro-pot group protesting Congress’ intervention into local marijuana policy did not cause an uproar on Capitol grounds Wednesday night, but they did clash with a congressman.

Rep. Emanuel Cleaver II, riding with his chief of staff in a black sedan, encountered a few of the most antagonistic individuals on Maryland Avenue Northeast. About two dozen demonstrators, mostly associated with the DC Cannabis Campaign, were blocking traffic following a brief protest at The Heritage Foundation’s nearby headquarters.

When the Missouri Democrat’s car pulled up to the intersection with D Street Northeast, a few protesters refused to let him pass. Cleaver leaned out the passenger side window and yelled that he had “somewhere” to be, but one man waving a “Legalize” flag stood in front of the car.
