The criminal investigation into the outing of CIA agent Valerie Plame's identity is casting a wide net. Remember Karen Hughes? President Bush's one-time communications aide. She quit the White House back in April, 2002. That's her in the picture at the left with President Bush.
She's been called and has testified before the grand jury investigating the leak.
She told the Senate Foreign Relations Committee about her appearances. She's appearing before them on her nomination to lead the State Department's public diplomacy effort.
Former White House spokesman Ari Fliesher (right) has also been called to testify because he got a telephone call from columnist Robert Novak the day after the outing. It was Novak, citing "senior administration officials" who first mentioned in print Valerie Plame's role in the CIA. Mr Fliescher says he never took the call that shows up on his telephone log. (IHT)
