President Barack Obama, retooling his economic team to boost sluggish U.S. growth and tackle emboldened Republicans, will on Friday name Gene Sperling as the new head of his National Economic Council.

A White House official said Obama will announce the appointment of Sperling, a trusted aide and Clinton-era veteran, in remarks at a window manufacturer in Maryland where he will also discuss the economy and December's job report.

Sperling's pick to replace Larry Summers at the economic council follows Obama's naming of a new chief of staff and the resignation of his press secretary, as the president shakes up his team after Republicans took control of the House of Representatives this week.

The NEC coordinates economic policy across the administration, and its head wields great influence within the White House.

Obama will speak at the Thompson Creek Window Co. in Landover, Maryland, at around 11:35 a.m. EST (1635 GMT), some three hours after the release of December's employment report.

Sperling, a counselor to Treasury Secretary Timothy Geithner, served as head of the NEC for President Bill Clinton between 1997 and 2000, and helped Clinton battle the Republicans and, eventually, balance the budget.

Obama, who must boost growth to ease U.S. unemployment stuck just below 10 percent or be punished in 2012's presidential election, on Thursday tapped another former Clinton aide, William Daley, an executive at J.P. Morgan Chase, as his chief of staff.

MID-TERM SHAKE-UP

Press Secretary Robert Gibbs also plans to step down early next month to become an outside adviser to Obama's re-election campaign.

The changes, as Obama enters the second two years of his term, reflect the White House's need to adapt to the new balance of power in Washington after Republicans won big against Obama's Democrats in November elections.

Republicans tapped into public fury over government spending and a $1.3 trillion budget deficit, and vow to use their increased congressional muscle to undo Obama's health-care reform program and curb federal borrowing.

Obama, who says he expects a tough debate over spending and taxes, late last year enlisted another old Clinton hand when he picked Jack Lew to lead the Office of Management and Budget.

In addition to Sperling, Obama will announce the promotion of Jason Furman to the number two slot at the NEC, the official said. Obama will also announce his plan to nominate Katharine Abraham to the White House Council of Economic Advisers and Heather Higginbottom as deputy director of OMB.
