U.S. President Barack Obama will unveil a 2012 budget plan later, which is expected to cut domestic spending.

Cuts are expected to hit home heating, community development and education, as Washington aims to cut $1.1tn (£690bn) from the U.S. deficit over a decade.
White House budget director Jack Lew told CNN that there were ""scores of programs"" that were being reduced.
Republicans, who control the House of Representatives, do not think the cuts go far enough in tackling the deficit.
House of Representatives Speaker, Republican John Boehner, told NBC the proposed budget would ""continue to destroy jobs by spending too much, borrowing too much and taxing too much"".
------------Long process
Analysts have also wondered if cutting $1.1tn will be enough.
""It's a lot less than the Republicans wanted to see,"" said Philip Poole, global head of macro investment at HSBC Global Asset Management in London.
""It's a start, it's a move in the right direction, but it's probably not enough in terms of what needs to be done ultimately, and it's not starting quickly enough.""
The deficit is to predicted to rise to $1.645tn in the 2011 financial year, then fall to $1.101tn in 2012.
The 2012 budget is a proposal to Congress laying out the president's policy priorities.
Mr Lew, director of the Office of Management and Budget, said he believed the president's budget would help ""the government live within its means, while still investing in America's future"".
But the two parties disagree over the level of spending cuts needed to cut the deficit and boost economic recovery.
Bringing them together will be a long process that takes most of the year before the required congressional approval of the budget.
-----------'Hard times'
The proposed $1.1tn budget reductions are much greater than the $400bn of cuts in non-essential programs the president unveiled in his State of the Union address last month.
Mr Obama is also believed to be about to give states more flexibility to pay for unemployment benefits.
And he is set to propose an $18bn plan to improve high-speed internet access, and a further $8bn for high-speed railways.
In his weekly message to the nation on Saturday, Mr Obama said the government would have to tighten its belt.
""This budget asks Washington to live within its means, while at the same time investing in our future,"" he said.
""It cuts what we can't afford, to pay for what we cannot do without.
""That's what families do in hard times. And that's what our country has to do too.""
