The Associated Press is already reporting before the 2:15 p.m. press conference that Vice presidential adviser I. Lewis "Scooter' Libby Jr. will resign today after being charged with obstruction of justice, perjury and making a false statement in the CIA leak investigation in a politically charged case that could throw a spotlight on President Bush's push to war in Iraq.

Karl Rove, Bush's closest adviser, escaped indictment Friday but remained under investigation, his legal status a looming political problem for the White House.

The indictment charged Libby, 55, with one count of obstruction of justice, two of perjury and two false statement counts. If convicted on all five, he could face as much as 30 years in prison and $1.25 million in fines.

The charges stem from a two-year investigation by special counsel Patrick Fitzgerald into whether Rove, Libby or any other administration officials knowingly revealed the identity of CIA officer Valerie Plame or lied about their involvement to investigators.

Libby is accused of lying about how and when he learned about Plame's identity in 2003 and told reporters about it. The information on the officer was classified.

He is also accused of lying when he told Fitzgerald's investigators that he learned about Plame's CIA status from Tim Russert of NBC. He learned it from Cheney, the indictment says.
