Patient rights advocates are criticizing a loophole in the Senate healthcare reform bill that would allow insurance companies to limit healthcare benefits even for seriously ill patients. An earlier version of the bill had banned the annual caps, but it’s since reappeared as the bill moves through committee. On Thursday, single-payer activists protested at Senate offices nationwide against the Democrats’ latest agreement to abandon the public option. Nine people were arrested at the New York offices of Democratic Senator Charles Schumer.
