Cracks in support throws Bolton bid

Unexpected cracks in Republican support threw into limbo President George W. Bush's high-profile nomination of John Bolton to be the country's UN representative.

The delay in a Senate committee vote handed Bush a political defeat, at least in the short term, and possibility the nomination could fail.

A few Republicans on the Senate Foreign Relations Committee joined Democrats in asking to delay a vote on Bolton, after "a lot of reservations surfaced", apparently including allegations of abusive personal behaviour by Bolton.
