* Obama to propose domestic spending freeze in FY 2011
* Three-year spending hold-down excludes U.S. security
* Savings to add up to $250 bln over 10 years-officials

WASHINGTON, Jan 25 (Reuters) - U.S. President Barack Obama, under pressure from deficit hawks, will seek a three-year freeze on domestic spending in his 2011 budget that would save $250 billion by 2020, administration officials said on Monday.
Obama will outline the spending hold-down in his State of the Union address on Wednesday and will spell it out in detail on Feb. 1, when he unveils his second budget.
Obama is under fire for a record deficit and has called for a bipartisan congressional commission to consider spending cuts and tax increases to improve the country's fiscal outlook.
His proposed budget savings will need congressional backing and would exclude Defense, Veteran Affairs, Homeland Security and spending on international affairs, the officials said.
"We are in the midst of fighting a war and have security needs. We're going to fund those security needs as necessary," one of the officials told reporters, speaking on condition of anonymity.
The officials declined to detail which agencies or programs would be hit, but said the overall freeze in so-called discretionary non-security spending would not halt investment in some areas, and would be balanced by cuts elsewhere.
Adjusted for inflation, the freeze would mean effective budget cuts in those areas of spending, the officials said.
Republicans dismissed the move as window-dressing by Obama's Democrats after an "unprecedented spending binge."
"This is like announcing you're going on a diet after winning a pie-eating contest," said Michael Steel, spokesman for House of Representatives Republican leader John Boehner.
The 2010 budget allocated $447 billion to non-security discretionary spending, or about one eight of the overall budget. Agencies that could feel the pinch include the Commerce, Interior, Justice and Labor departments, as well as the Environmental Protection Agency.
The United States ran a record $1.4 trillion budget deficit in fiscal year 2009.
Part of the problem, on top of a severe recession that hit government revenue, are entitlement programs like social security and Medicare, the huge public healthcare program for older Americans.
Obama wants to reduce soaring Medicare costs through an overhaul of the $2.5 trillion U.S. healthcare system, but his reforms are bogged down in Congress.
The officials said the proposed freeze would not affect entitlement programs but argued it could help set a tone of fiscal discipline.
"Imposing discipline here is one part of an overall picture and ... helping to create a new atmosphere of fiscal discipline ... can actually also feed into debates over other components of the budget," one of the officials said.
The freeze would cut the deficit by between $10 billion and $15 billion in fiscal 2011. A total of $250 billion would be wrung from the budget by 2020, they said.
But, the impact would not undermine the economy's recovery after the most prolonged contraction in 70 years.
"From a macro-economic perspective, I don't think there will be a huge affect in 2011," the official said. (Reporting by Alister Bull; editing by Anthony Boadle)
