New England head coach Bill Belichick spoke exclusively with CBS reporter Armen Keteyian this afternoon, and the interview was just broadcast on the CBS Evening News. Belichick spoke on camera for the first time about Matt Walsh, the former video assistant who spoke with NFL commissioner Roger Goodell and Sen. Arlen Specter this week about the Pats' videotaping practices when he was an employee of the team.

Here's what Belichick had to say:

On Walsh and his possible reason for becoming part of the Spygate story:
I don’t know what the agenda is. You know, again, he was fired here for poor job performance. There’s not a lot of credibility. He’s tried to make it seem like we were buddies and belong to the same book club and all that is really a long, long stretch.

More on Walsh and his role with the team:
For him to talk about game planning and strategy and play-calling and how he advised coordinators is…it’s embarrassing, it’s absurd. I mean, he didn’t have any knowledge of football – he was our third video assistant.

On Walsh's assertion that he was told to avoid detection while taping; the Patriots gave CBS tape which show Walsh behind a camera, in plain sight, and in team gear:
Why say he was told to avoid detection? I never told anybody to tell him that. All I can tell you is what the facts are – you look at the tape, you’ve seen film of the game. You tell me how discreet it is.

On the memo circulated by the league outlining illegal videotaping practices, which Belichick knew of and found to be in violation of:
I made a mistake. It was wrong. I was wrong.

What Belichick says to those who say his team cheated its way to Super Bowl titles:
I’ve said to you…I’ve told you the truth.
