The Senate Armed Services Committee voted to move Defense Secretary nominee Chuck Hagel's confirmation to the Senate floor.
Committee Republicans expressed concerns over the former Nebraska senator's nomination.
A group of Republican senators sent Chairman Levin a letter, demanding that Hagel turn over more information about his finances and funding he may have received from foreign powers.
Majority Leader Harry Reid (D-NV) said he would bring up the Hagel nomination for a floor vote on Wednesday if the committee approves the nominee.
