Peterborough, New Hampshire (CNN) - Mitt Romney said Saturday he would not support any deal by a congressional debt committee that raised taxes, even as time ran short on a deficit-reduction agreement in Congress.
"I don't believe that raising revenues is the right answer to balancing our budget," he said. "I will not support any proposal based upon increasing taxes or revenues. I will, however, support proposals that are focused on reducing spending."
Romney was asked about a proposal by Republican Sen. Pat Toomey that included $400 billion in additional tax revenue - anathema to many congressional Republicans - as part of deficit reduction.
Romney said he had not seen the plan, but said the "right answer" was to concentrate on spending cuts and entitlement reform.
"In my view, what the super committee should do is rein in excessive spending in the current budget and reform Medicare and Medicaid and Social Security to make them permanently sustainable," he said.
Speaking to members of the press en masse for the first time in several days, Romney also said he planned to spend more time in Iowa as the January 3 caucus date nears.
Many of his opponents were in Iowa the same night, speaking at a Family Leader presidential forum.
"We've missed a couple of events in Iowa but I've been there several times.
I've said from the very beginning that we intend to play in Iowa, that I want to do very well there," he said. "You can also expect as we get closer to the caucuses and to the primaries, you'll see us visiting those early states more, spending more time there turning out more volunteers and being more active."
The former Massachusetts governor opened a campaign office in first caucus voting state last week. Romney poured money into the Iowa contest last election cycle only to yield disappointing results, and has visited the state only sporadically this campaign.
But a fluid GOP field in which many social conservatives have risen and then fallen in the polls may convince Romney's staff that Iowa could be viable for him.
Romney also defended the actions his former staff took in 2006 after he served as governor of Massachusetts. The Boston Globe reported Romney's aides purchased 17 computer hard drives that had been used in the governor's office after his term.
Romney said the hard drives could have contained private, confidential information such as medical records or resumes.
"Hard drives have the information of emails," he said. "They have information which can be confidential and private and which can be obtained."
He explained: "They may have personal information on there, medical records, resumes from people who have applied for jobs, or judicial appointments made and people applying for those positions. Those are confidential, of course. And so items that are personal or confidential, of course, would not be appropriate to put them in the public domain. We'd be violating our trust in doing so."
