The first family's longtime personal chef is leaving the White House.

The White House says the newly married Sam Kass is moving to New York, where his wife lives. Kass has worked for the first family since President Barack Obama was in the Senate.

Kass moved to Washington after the 2008 presidential election to serve as the Obamas' primary chef. But he has also taken on policy work, serving as executive director of first lady Michelle Obama's anti-childhood obesity initiative and becoming the White House's first-ever senior adviser on nutrition.

In a statement, Obama says Kass "has made a real difference for our next generation." Mrs. Obama says Kass will "continue to be a leader in the vitally important work to build a healthier country."
