Sen. Kelly Ayotte on Sunday criticized President Obama's upcoming 2015 budget proposal, which will call for new spending for domestic programs while abandoning a previous plan to slow the cost-of-living increases for Social Security.

The forthcoming document is seen as a rejection of the austerity measures -- namely the automatic spending cuts known as the sequester -- that Republicans have pressured Democrats to accept during Obama's tenure in the White House.

Speaking on "Fox News Sunday," Ayotte (R-N.H.) questioned characterizations of  the past several years as an "era of austerity."

"Since the president has been in office, we've added $6 trillion more to the debt, so we're over $17 trillion in debt," she said. "There hasn't been an 'age of austerity,' and it's really disappointing that the president hasn't stepped up to lead this effort of a deal that needs to be done for the nation."

"To see this budget, it's really a political document," Ayotte continued. "It's not what we need for America when we're $17 trillion in debt."
