Nixonian

AP:

President Bush, moving toward a constitutional showdown with Congress, asserted executive privilege Thursday and rejected lawmakers' demands for documents that could shed light on the firings of federal prosecutors.

Bush's attorney told Congress the White House would not turn over subpoenaed documents for former presidential counsel Harriet Miers and former political director Sara Taylor. Congressional panels want the documents for their investigations of Attorney General Alberto Gonzales' stewardship of the Justice Department, including complaints of undue political influence.

The Democratic chairmen of the two committees seeking the documents accused Bush of stonewalling and disdain for the law, and said they would press forward with enforcing the subpoenas....

''Increasingly, the president and vice president feel they are above the law,'' said Senate Judiciary Chairman Patrick Leahy, D-Vt. He portrayed the president's actions as ''Nixonian stonewalling.''

Hmmm. How did Congress deal with Nixon?
