From the Washington Post:

Specter’s letter accused Cheney of going behind his back to forge an agreement with other Republican members of his committee to prevent testimony from the executives of three major phone companies that reportedly provided a huge cache of call records to the National Security Agency.

“These communications are not unusual — they are the government at work,” Cheney wrote.
The two men later spoke by phone in what an administration official called a cordial conversation, though no other details emerged.

SPECTER: You called me.

CHENEY: Huh? Hrklkrkle…

SPECTER: The whole thing’s out of control, isn’t it?

CHENEY: Hrrff?

SPECTER: It’s because, thanks to the powers that you’ve given the NSA, the ones we know about and the ones we’ve yet to learn, not a single line in this nation is secure. Not even your own damn phone. Is that it? Is it?
