Senate Minority Leader Mitch McConnell (R-Ky) called on the Protect IP Act to be shelved for the forseeable future. Senate Majority leader Harry Reid still plans to bring the legislation to the floor on Tuesday, but the defection of Republicans has raised doubts on whether he will have enough votes to overcome a threatened filibuster.

McConnell said, “While we must combat the on-line theft of intellectual property, current proposals in Congress raise serious legal, policy and operational concerns.

He added, “Considering this bill without first doing so could be counterproductive to achieving the shared goal of enacting appropriate and additional tools to combat the theft of intellectual property. I encourage the Senate Majority to reconsider its decision to proceed to this bill.”
