White House blocking congressional Plame probe, chairman says

President Bush is doing everything possible to delay, obfuscate and obstruct a congressional investigation of his possible role in exposing an undercover CIA agent, a Congressional chairman alleges.

Rep. Henry Waxman, chair of the House Oversight Committee, has challenged new Attorney General Michael Mukasey to demonstrate his independence from the White House, just as Clinton-era AG Janet Reno did in handing over documents related to the president and vice president.
