The Bowles-Simpson deficit-reduction plan proposes cutting $4 trillion over 10 years.
Lawmakers are bracing for news Monday that the supercommittee will be unable to meet its mandate of finding $1.2 trillion over 10 years in federal deficit cuts. Manchin has been critical of the committee's progress, warning them that "failure cannot be accepted" and criticizing Obama for not taking a more active role in negotiations. On Sunday, Manchin said the president needed to "step forward" and push panel members to reach a deal.
