Former Vice President Dick Cheney and other Bush administration officials may be called to speak before the Senate Intelligence Committee "down the line," its chairwoman said Monday.

"Well, we well may down the line call some people," Feinstein said in response to a question on CNN about whether Cheney and other former top intelligence officials would be asked to speak about the program.

But the California Democrat insisted the process be balanced and not driven by a political agenda.

"It's not my interest to get into recrimination or blame at this stage," she said. "I think it should be driven by a very evenhanded investigation of what did go on."

Feinstein said there was evidence that the CIA had never been briefed on the Bush administration plan, which was reportedly involved in targeting top terrorist leaders.

Feinstein did praise the actions of current CIA Director Leon Panetta, though, for canceling and disclosing the program to lawmakers once he discovered it.

"And so when Mr. Panetta came in and said, look, I just learned about this program, I'm canceling it as of today, he did exactly the right thing," she said.
