Mr Obama said $85bn (£55bn) in cuts was a harmful, "meat-cleaver approach" to deficit reduction, as he stood with emergency workers at the White House. He also offered targeted spending cuts, supporting a proposal similar to that outlined by Senate Democrats last week. Mr Obama has just returned from a three-day golf trip in Florida. Fresh from his weekend round of golf with Tiger Woods, the president said: "These cuts are not smart, they are not fair, they will hurt the economy. This is not an abstraction. People will lose their jobs."
'Blocking tax reform'
The president added that the effect of the so-called sequester was already being felt in some government departments, noting the Navy had delayed the deployment of a carrier to the Gulf. "Changes like this, not well thought through, not phased in properly, changes like this affect our ability to respond to threats in unstable parts of the world," Mr Obama said. He also said that while he was open to cutting back on unsuccessful or unnecessary government programmes, he accused Republicans of "ideological rigidity" for opposing tax increases. He proposed closing some tax loopholes to increase revenue, and backed a budget plan put together by Senate Democrats last week.
Mr Obama said the deep, across-the-board spending cuts had originally been designed to be so unattractive that they would spur politicians to work together. Congressional Republicans have given a frosty reception to the Senate Democrats' proposal. They point out that Mr Obama already won a revenue increase in the new year, when Congress allowed taxes to rise on families making more than $450,000 annually.
In response to the president's remarks, House Speaker John Boehner said: "The American people understand that the revenue debate is now closed. "Tax reform is a once-in-a generation opportunity to boost job creation in America. It should not be squandered to enable more Washington spending. Spending is the problem, spending must be the focus," a statement said. Congress is in recess this week, leaving even less time to negotiate a budget solution ahead of the 1 March deadline.
