Specter said he would prefer the NFL arrange the independent investigation and was willing to wait several months — while he continues to undergo chemotherapy treatments for Hodgkin's disease — before calling for Congress to take what he called "corrective action." Such action could include hearings or a full-blown Mitchell Report-type investigation. He said public reaction would determine the NFL's next step.

"I would hope that the commissioner would do this on his own," Specter said.

Patriots spokesman Stacey James said the team had no comment on Specter's remarks.

Earlier Wednesday, the Boston Herald apologized for a story that said the Patriots videotaped a St. Louis Rams walkthrough before the 2002 Super Bowl.

In the apology, published in the newspaper's Wednesday edition and posted on its Web site, the Herald said the story was based on sources "it believed to be credible."

"We now know that this report was false, and that no tape of the walkthrough ever existed," the paper wrote.

"We should not have published the allegation in the absence of firmer verification. The Boston Herald regrets the damage done to the team by publication of the allegation, and sincerely apologizes to its readers and to the New England Patriots' owners, players, employees and fans for our error."

Specter repeated his disapproval of Goodell's decision to destroy the notes and tapes confiscated during the initial investigation last fall, as well as the "piecemeal" way the league has revealed details about the tapings. He also cited the fact a Patriots attorney sat in on Walsh's meeting with Goodell as proof the investigation has not been impartial.

"That sequence is incomprehensible," Specter said. "It's an insult to the intelligence of the people who follow it."

Specter's interest in Spygate centers in part on the two NFL teams in his state. The Philadelphia Eagles lost to the Patriots in the Super Bowl in 2005, the same season in which the Steelers were defeated by New England in the AFC championship game.

Pittsburgh defeated New England earlier that season, and the implication is that taped signals from that game helped the Patriots in the rematch. Steelers chairman Dan Rooney has called the matter a "non-issue."

"I have a different perspective," Specter said. "I'm elected by 12 million people, and a lot of them are Steeler fans. ... Frankly I'm incensed about what happened with the Steelers, and I'm incensed about the notes being destroyed. I really am."

Specter was again asked whether his interest in the matter has to do with Philadelphia-based Comcast, one of his largest campaign contributors. Comcast has been involved in a dispute with the league over the placement of the NFL Network on its cable system.
