[JURIST] The federal grand jury investigating the leak of a CIA operatives identity [JURIST news archive] adjourned on Wednesday after meeting for three hours with Special Counsel Patrick Fitzgerald [official profile; investigation website] and his deputies. The grand jury's term, which is set to expire in three days, can be extended by Chief US District Judge Thomas Hogan [official profile] at Fitzgerald's request. Though Fitzgerald met with Hogan [AP report] Wednesday prompting speculation that there will be an extension, White House lawyers expect Fitzgerald to decide this week whether to charge chief presidential adviser Karl Rove [Washington Post profile] and Vice President Dick Cheney's chief of staff I. Lewis "Scooter" Libby [official profile]. The two-year investigation began when the identity of CIA operative Valerie Plame [Wikipedia profile] was revealed days after her husband, Ambassador Joseph Wilson, criticized the Bush administration's pre-Iraq war intelligence.
