Attorney General, Alberto Gonzales, continues to face heat over the firing of eight federal prosecutors.
Gonzales has told Congress he was not taking direction from the Bush administration, but e-mails released late March 15, 2007, show the president's top adviser, Karl Rove, discussed the termination within the White House.
A Senate panel has approved the subpoenas of five justice department officials.
The rhetoric against Gonzales is growing. Several Republicans have joined the chorus of Democrats calling for Gonzales to resign.
The White House continues to stand behind him.
