Former House Speaker Newt Gingrich (R-Ga.) dismissed attention to his campaign's difficulties as "irrelevant" amid high levels of unemployment.
Gingrich renewed his attacks toward the media on Monday for concentrating on the departures of top campaign officials and fundraisers.
"I think the turmoil is, frankly, irrelevant," Gingrich said during an appearance on Fox News.
The former Speaker has been combative about the state of his campaign, which observers have claimed is teetering on collapse after a tough rollout and fundraising that's expected to be lackluster.
"I'm prepared to talk about substance longer than the news media, hopefully, can talk about gossip," he said. "Nobody in Indianola, not a single person, asked me a single question that dominate the elite media."
Gingrich rejected the notion that his wife, Callista, or any other figures have too strong of a role in his campaign ("I run my own campaign," he said Monday), and last week vowed to keep his bid for the Republican nomination alive long enough to compete in Iowa's caucuses early next year.
The Georgia Republican has said he wants to run an "ideas" and "solutions"-driven campaign, and he offered one on Monday to House Republicans facing a political showdown with President Obama on raising the debt limit.
The House GOP, Gingrich said, should find out by how much Obama is willing to cut in spending, and then agree to raise the debt ceiling by the same amount and "not a penny more." That strategy, the former Speaker argued, would help insulate Republicans from political fallout if there's a breakdown in talks toward a grand bargain to raise the debt ceiling before the early August deadline.
Meanwhile, Gingrich accused Obama of abdicating responsibility in the debt debate.
"I reject the Obama technique of pretending he's not president of the United States," he said.
