Two women who chained themselves to the Grant Street entrance of Downtown's Grant Building released themselves from the revolving doors at around 8:40 this morning, ending a small demonstration against U.S. Senator Pat Toomey's support for a controversial tax plan passed in the small hours of Saturday morning. Those working in the building, which houses Toomey's Pittsburgh office, were told to use a side entrance -- and to blame Toomey's vote for any inconvenience.
