The Center for American Progress considers the relationship between Pfizer's donations for Schwarzenegger's accomodations in New York and the veto he's mulling: Gov. Arnold Schwarzenegger's administration threatened late Thursday that he would veto four bills designed to help Californians buy cheaper prescription drugs from Canada unless the measures are amended. The signal was the administration's first public stance on the populist measures, which have pitted doctors, labor interests and senior citizens against business groups and pharmacists, who are among the governor's top backers. It was also the first public push to block a controversial bill from reaching Schwarzenegger's desk in the final weeks of the session. The administration has been privately wrestling with how to stop controversial bills flowing from the Legislature to the governor.
