Sen. Arlen Specter (R-Pa.) is scheduled to meet Tuesday with a former New England Patriots assistant who has turned over eight tapes that reportedly show the three-time Super Bowl champions filming opponents' play-calling signals.

Matt Walsh, a former video assistant for the Patriots from 2000 to 2002, has given tapes to the National Football League of signals in six Patriots games, including the 2002 conference championship game between New England and the Pittsburgh Steelers, reports the Boston Herald.

The NFL docked the Patriots their 2008 first-round draft choice for filming the signals of the New York Jets during a 2007 game.

Specter has criticized the NFL's decision to allow the tapes of the Jets' signals to be destroyed. Specter has also said that he could call on NFL Commissioner Roger Goodell to testify about the "Spygate" controversy in a Senate committee hearing over the league's federal antitrust exemption.
