Grassley is just the latest in a string of Republican Senators to reverse their previous support for PIPA on Wednesday including Sens. Marco Rubio (R-Fla.), Roy Blunt (R-Mo.), John Boozman (R-Ark.) and Orrin Hatch (R-Utah). Their reversals came in the wake of massive online protests against the legislation.
Grassley's statement indicates he is open to changes to address concerns the bill would lead to censorship and stifle innovation online. His office clarified that he is not withdrawing his formal sponsorship of the bill, which is heavily supported by the entertainment industry, the U.S. Chamber of Commerce and organized labor.
