[JURIST] The Washington Post reported [full text] Wednesday that a far wider range of White House officials than originally known have been interviewed by prosecutors investigating the Valerie Plame leak. The probe has questioned former CIA director George J. Tenet [Wikipedia profile] and deputy director John E. McLaughlin, and former CIA spokesman Bill Harlow. Part of the investigation has also centered around White House blame-shifting for disputed assertions in the 2003 State of the Union address [transcript] that Iraq was trying to obtain nuclear material from Africa. Reports are circulating that White House officials including Vice President Dick Cheney's chief of staff Lewis Libby [Wikipedia profile; JURIST report] and chief presidential adviser Karl Rove [JURIST report] were involved in the Plame leak, but the White House has denied any wrongdoing by either [JURIST report].
