Jefferson's office was contacted by the FBI before they went to a judge, and his office denied the FBI access. And now we know why.
The judicial branch granted the FBI the authority to search the Congressman's office after the FBI presented enough of a case to support the need to search for evidence of a felony.
What would possibly protect a Congressman, who at last count is an American citizen and subject to American law, from being investigated?
What I don't understand though is didn't the FBI search Gary Condits apartment (and maybe office, not sure) and I don't remember hearing this big out cry then.
