[JURIST] The US Senate was forced to delay the vote on UN ambassador nominee John Bolton [official biography] Thursday after Democrats demanded more information from the White House before agreeing to end their debate which began Wednesday [JURIST report] and vote on the nomination. Democrats say that the Senate has not been given classified information on Bolton's current position as the State Department's arms control chief. Republicans needed 60 votes to end the debate, but the roll call was only 56-42. Majority Leader Bill Frist released a statement [press release] after the vote stating the "Democrats have chosen partisan confrontation over cooperation." Due to the Memorial Day recess, the confirmation vote will probably not be taken until June. AP has more.
