President Obama will announce Friday that his top White House economic adviser, Gene Sperling, will leave at the end of the year and be replaced by Obama’s former budget director, Jeff Zients, a White House official said.

National Economic Council director Gene Sperling, who also played that role in the Clinton administration, will be leaving so he can join his wife in California. He spent the first two years of Obama's first term as a senior adviser to then-Treasury Secretary Timothy F. Geithner and later moved to the White House, where he coordinates economic policy.
