The automatic cuts were included in this past summer's debt-ceiling deal as a last resort should the 12-member, bipartisan and bicameral panel fail to reach a deal by Nov. 23.
Defense Secretary Leon Panetta has warned that forced military cuts would “undermine our ability to meet our national security objectives and require a significant revision to our defense strategy.”
One sticking point in the stalled supercommittee negotiations was Republican resistance to raising taxes in order to increase revenue, something that Romney also opposes.
"There will be a lot of give and take of proposals made and yet I will not support any proposal based upon increasing taxes or revenues. I will support proposals reducing spending," Romney said over the weekend.
Romney also blamed President Obama for failing to lead in the deficit negotiations, saying "our president has had no involvement with the process."
Most of the other Republican presidential candidates had also voiced their criticism by Monday of Obama for failing to lead Congress to a deal.
However, the White House deflected blame back on Congress in Monday's press briefing.
“Congress assigned itself a job, assigned 12 of its own members a task, a task that wasn’t really that difficult to achieve,” White House press secretary Jay Carney said. “There wasn’t a seat at that table, as far as I’m aware, for a member of the administration.”
"I don't disagree that [Obama] wasn't having one-on-one conversations with the Speaker of the House here in the White House on this," Carney said.
He added that “throughout the summer [Obama] was engaged directly and personally” in negotiations and had presented a proposal to Congress including cuts that went beyond the supercommittee's mandate in September.
