A procedural "violation" in the historic U.S. health care reform bill means the legislation must be returned to the House of Representatives for a new vote.
A spokesman for Democratic Senate Majority Leader Harry Reid says Republicans found "two minor and technical provisions" in the bill that violate budget rules.
The two provisions deal with federal government grants to help low-income students pay for university studies.
Spokesman Jim Manley said the two provisions must be removed from the bill.
The Senate would then have to pass the measure -- sending it back to the House of Representatives for approval again before Obama can sign it into law.
Manley said he is confident the House would approve the legislation with no problems.
