Goodling, one of several aides involved in the firings of federal prosecutors, will refuse to answer senators' questions.

"The potential for legal jeopardy for Ms. Goodling from even her most truthful and accurate testimony under these circumstances is very real," Dowd said. Goodling was key to the Justice Department's political response to the growing controversy. She took a leave of absence last week.

"One need look no further than the recent circumstances and proceedings involving Lewis Libby," Dowd said, a reference to the recent conviction of Vice President Dick Cheney's former chief of staff in the CIA leak case.

Leahy swiftly cast doubt about Goodling's motives.

"The American people are left to wonder what conduct is at the base of Ms. Goodling's concern that she may incriminate herself in connection with criminal charges if she appears before the committee under oath," said Leahy.

Dowd shot back in a second letter that Leahy's comments were a good illustration of why testifying was "perilous" for his client.

"It is the politically charged environment created by the members of the committee ... that has created the ambiguous and perilous environment in which even innocent witnesses would be well advised not to testify," Dowd wrote.

Democrats allege the firings were a purge of those deemed by the Justice Department not to be "loyal Bushies" _ and a political warning to other prosecutors to fall in line with the administration. Gonzales has denied that.

The news of Goodling's refusal to testify toughened an already daunting week for Gonzales, who retains Bush's support, apparently on condition that he patch things up with Congress. There was little sign of that happening.

Republicans over the weekend lobbed new criticism at Gonzales and more Democrats called for his resignation. Gonzales, meanwhile, was in Denver on Monday, leading a round-table discussion on curbing child sex abuse. He was expected to remain out of town most of the week.

But Goodling's announcement appeared to be an unforeseen piece of bad news for Gonzales' agency, which had no immediate comment.

Sen. Chuck Schumer, D-N.Y., who is leading the Senate's investigation into the firings, said Deputy Attorney General Paul McNulty told him he was misled by other Justice Department aides before he testified to Schumer's panel on Feb. 6.
