US leaders squabble despite dire cuts warning

US Fed chairman Ben Bernanke Tuesday sounded the alarm over huge budget cuts looming within 72 hours, but political leaders traded blame rather than fixing a row threatening the fragile economy.

President Barack Obama traveled Tuesday to a Virginia shipyard that builds nuclear-powered aircraft carriers and submarines for the US Navy, amid fears the cuts, known as the sequester, will damage America's defense readiness.

Republicans meanwhile accused him of exploiting the military and refused to accept his demand to raise more taxes on the rich as part of the solution to the showdown over $85 billion in cuts due to hit on Friday.

Bernanke, in prepared testimony to Congress, cited data from the Congressional Budget Office predicting that the cuts in defense and discretionary domestic spending could reduce economic growth by 0.6 percent.

"The Congress and the administration should consider replacing the sharp, front-loaded spending cuts required by the sequestration with policies that reduce the federal deficit more gradually," he said.

"Given the still-moderate underlying pace of economic growth, this additional near-term burden on the recovery is significant."

Obama was expected to paint a devastating picture of damage from the cuts, which some estimates say could cost one million jobs, as he seeks to lock in a political advantage over Republicans.

The White House said the sequester would see 90,000 civilian defense workers furloughed in Virginia alone and would delay maintenance of 11 naval vessels.

It warns of a "perfect storm" of airport delays and less secure US borders when cuts happen, says pre-school programs could be hit, teachers will be laid off, emergency services will see funds cut and public services will be reduced.

Republicans accuse the president of resorting to scare tactics.

Obama Tuesday was expected to accuse Republicans of protecting wealthy supporters and corporations by refusing to close tax loopholes while placing the burden for sequester cuts on the already struggling middle class.

Republicans are balking at raising new revenue, after losing a showdown with the newly re-elected president last year over raising tax rates on the rich.

They say they are willing to close loopholes, but only in the context of a sweeping overhaul of the tax system which could see rates for the wealthy fall.

Republican House Speaker John Boehner accused Obama of using "military men and women as a prop in yet another campaign rally to support his tax hikes."

And he rejected the notion that Republicans had done nothing to stop the sequester, as the Republican House has voted twice to reframe the cuts -- though the bills lack the revenue hikes Obama is demanding.

"We should not have to move a third bill before the (Democratic-led) Senate gets off their ass and begins to do something," Boehner said.

The idea for the automatic, arbitrary budget cuts emerged as a way to ease a previous spending showdown between Obama and Republicans in Congress.

The massive reductions to the military and domestic budget were supposed to be so severe that both sides would be forced into a deal to cut the deficit. But Washington is so dysfunctional that no agreement has been reached.

Senate Republican minority leader Mitch McConnell said Obama was blaming political foes for the consequences of his own actions.

"The President's been running around acting like the world's going to end because Congress might actually follow through on an idea he proposed and signed into law -- all the while pretending he's somehow powerless to stop it.

"Should these cuts be implemented in a smarter way? Absolutely.

"But the President and his cabinet secretaries ... can't just show up now at the last minute and expect the American people to bail them out of their own lack of responsibility," McConnell said.

The White House argues that Republicans are equally to blame for the sequester, as it was passed by both chambers of Congress before Obama signed it into law.

There seems little prospect that Washington's feuding politicians will agree to halt the sequester before it comes into force on Friday.

The first point of possible compromise may then come with a bill due at the end of March to fund the government's operations.
