A decision is expected today on charges over the leak of a covert CIA operative’s identity. Karl Rove, President George W. Bush’s top political adviser, may escape being charged with making false statements to a grand jury. However, Lewis Libby, chief of staff for Vice President Dick Cheney, is likely to face indictment. Both men spoke to reporters in June and July 2003 about the CIA operative Valerie Plame- something the White House initially denied. Plame’s identity was leaked to the media after her diplomat husband, Joseph Wilson, accused the Bush administration of twisting intelligence on Iraq to justify the invasion.Any indicted officials are expected to immediately resign. It would be a major headache for an administration already embarrassed by the withdrawal of President Bush’s nominee to the US Supreme Court, Harriet Miers. Miers, a Texan who has been a corporate lawyer but never a judge, withdrew after attracting fierce criticism from both Democrats and Republicans. Conservatives argued Miers was not committed enough to banning abortion. It has been a bad week for Bush whose personal ratings dropped to 37 per cent as the US military death toll in Iraq reached 2,000.
