Look who’s watching YouTube movies now: California Gov. Arnold Schwarzenegger is calling for the state's attorney general to launch an investigation into ACORN, the liberal nonprofit, in the wake of conservative activists releasing undercover videos online that showed some of the group's employees giving advice on how to set up a prostitution ring and other crimes straight out of a Law & Order plotline. Schwarzenegger’s concerns are about ACORN’s San Bernardino branch, where the conservative filmmakers posed in outrageous pimp-and-ho costumes and queried a haggard ACORN employee on "how not to get caught" with their business. The ACORN employee also talks about how she shot her ex-husband and "laid some groundwork" before going to a domestic-violence shelter. The U.S. Senate voted to block federal housing grants to ACORN on Monday.
