Rep. Howard Berman is accusing his Democratic colleague and competitor Rep. Brad Sherman of using his political campaigns as a vehicle for personal profit.

The Berman campaign launched a website, Sherman-Scam.com, to highlight the legal practice of charging interest on personal loans to his campaign, which it says helped Sherman make a profit of $461,000. The campaign also plans to deliver this message to San Fernando Valley voters in the redrawn 30th district with television, radio, print and online advertisements.

The Sherman campaign called the attack “false at worst and highly misleading at best” and cited the hundreds of thousands of dollars Berman paid his brother, Democratic consultant Michael Berman, to run his campaign until this cycle.

Neither practice is illegal, but both campaigns want to help voters decide which candidate is the most ardent defender of the Valley’s interests.
