Republican budget hawk Paul Ryan unveiled a fiscal plan on Tuesday that he claimed would balance the US budget in 10 years by cutting federal spending but without raising taxes.
Ryan, chairman of the House budget committee, presented his budget – which calls for the repeal of Barack Obama's health reforms – as a starting point for negotiation with the Democrats.
But the White House rejected it out of hand. "The math just does not add up," it said in statement, describing it as "the wrong course for America".
The Republican budget came as president Barack Obama was heading to Capitol Hill to meet Senate Democrats. It will be the first of four meetings over the next three days with members of Congress from both parties that he says is aimed at finding a compromise on tax and spending.
