The relevant provision, 18 U.S.C. § 1505, is very broad. It is illegal to lie to Congress, and also to “impede” it in getting information. Deputy Attorney General Paul McNulty indicated to Congress that the White House’s involvement in firing the United States attorneys was minimal, something that Justice Department e-mail messages suggest to be untrue.
David Iglesias, the New Mexico United States attorney, says Senator Pete Domenici, Republican of New Mexico, called him and asked whether he intended to bring indictments in a corruption case against Democrats before last November’s election. Mr. Iglesias said he “felt pressured” by the call. If members of Congress try to get a United States attorney to indict people he wasn’t certain he wanted to indict, or try to affect the timing of an indictment, they may be violating the law.
18 U.S.C. § 1512 (b) makes it illegal to intimidate Congressional witnesses. Michael Elston, Mr. McNulty’s chief of staff, contacted one of the fired attorneys, H. E. Cummins, and suggested, according to Mr. Cummins, that if he kept speaking out, there would be retaliation. Mr. Cummins took the call as a threat, and sent an e-mail message to other fired prosecutors warning them of it. Several of them told Congress that if Mr. Elston had placed a similar call to one of their witnesses in a criminal case, they would have opened an investigation of it.Presidents can not just fire any prosecutor, even if they are hired and fired by him. They can only fire an attorney if the firing will not corruptly obstruct, influence, or impede an official proceeding.
