Mayor Bloomberg reportedly ripped into Senator Kirsten Gillibrand in a phone call this week over the health-care bill’s treatment of New York (even though Charlie Rangel insists he’ll fix everything), according to someone who may have been eavesdropping. “The mayor really gave Gillibrand a piece of his mind over the damage the bill will do the city,” the source claims. Bloomberg also called the state’s other senator, Chuck Schumer, but he used a “friendlier” tone. Which is interesting, since Schumer was actually one of the chief architects of the Senate’s health-care-reform bill, and Gillibrand, as far as we can tell, hasn’t really had a say in it at all. Maybe Bloomberg has just heard how good Schumer is with a gun.
