Former clients are distancing themselves from Erik Brown, the California-based consultant in the spotlight for billing the Republican National Committee for a trip to a risqué Los Angeles nightclub.

California Assemblyman Chuck DeVore (R), who's running for Senate, announced Monday he "has severed all ties" with Brown's consulting firm, Dynamic Marketing, Inc (DMI).

The DeVore camp had been using DMI to print some campaign letterhead, signs and stickers, it said in a release. Their business dealings "ended some weeks ago when we contracted with a different printer, and will not resume."

"There is no present relationship with DMI," DeVore's camp said.

Meanwhile, others are speculating that Brown has become the RNC's fall guy for the public relations debacle.
