Goodling, however, told Congress that she did not hold the "keys to the kingdom" of understanding the controversy and said she never, in her role as the liaison to the White House, had a conversation with either top White House political adviser Karl Rove or then-White House counsel Harriet Miers about the firings.
She testified that she did not know why some of the names had been placed on the list and was unaware of anyone within the department "ever suggesting" that replacing the eight U.S. attorneys was in retaliation for the prosecutors refusing to prosecute a particular case for political advantage.
While some accounts have cast Goodling as a political operative in the department, Goodling described herself as a "fairly quiet girl" who "tried to do the right thing."
Goodling told the committee that while she served in the executive office of U.S. attorneys and on Gonzales' staff she reviewed hundreds of job applications for political appointees and career officials.
The hearing began amid a flurry of cameras clicking. Surrounded by her lawyers, Goodling was subjected to a 17-minute spray of cameras before the testimony actually got under way. Goodling spent nearly eight hours on the hill testifying and waiting for the hearing to resume after breaks for lunch and votes.
Rep. James Sensenbrenner, R-Wis., called the focus on the controversy "a fishing expedition," saying that so far, "we have found there ain't no fish in the water."
