Libertarian Rep. Ron Paul (R), who is considering a presidential bid, criticized the House Republicans' budget proposal during an appearance in Iowa on Monday. 

Paul said that the proposals from House Budget Committee Chairman Paul Ryan (R-Wis.) and President Obama don't do enough to solve the nation's oncoming fiscal woes.

"Neither of those budgets will solve our problems, won't even come close," Paul said during his talk at the Family Leader Presidential Lecture Series, according to Reuters

The veteran congressman often stakes out positions that are antithetical to his party's leaders, but has said he would remain on the Republican ticket should he run for president. 

Paul's position stands out from other potential 2012 GOP contenders, who last week largely praised the proposal to cut $5.8 trillion over 10 years. 

The congressman said that Ryan's budget plan does not do enough to reduce the amount of social welfare provided by the government. Other critics on the right have pointed to the fact it would not balance the federal budget for about two decades. 

His son, Rand Paul (R), a Tea Party-backed senator from Kentucky, is also circulating a "Dear Colleague" letter to members of the upper chamber urging them not to vote for a compromise on government funding for the rest of the fiscal year. 

Ryan spent much of last week defending his drastic proposal, saying that the amount of time his proposal would take to balance the budget is due to the profoundly deep fiscal problems facing the United States.

“This just shows you how deep a hole our country is in,” he said.

Paul said last week he would make a decision by May whether to make his third run for the White House.
