The top Senate Democrat who’s charged with ushering a smooth confirmation for President Obama’s pick to be the next Pentagon chief was forced to delay a final vote on the nomination, U.S. News has learned.

It is unclear what has caused the delay, though senators on both sides of the aisle have increasingly questioned Hagel’s aptitude for the job.
