President Obama and Hillary Clinton Meet for Lunch at White House

— -- It was lunchtime at the White House for President Obama and Democratic presidential front-runner Hillary Clinton today.

The former rivals-turned-amicable colleagues met privately for a 90-minute "informal lunch" at the White House, White House Press Secretary Josh Earnest said.

"When their schedules permit, President Obama and Secretary Clinton enjoy the opportunity to catch up in person," Earnest said.

The lunch was not on Obama's or Hillary Clinton's public schedules, and the White House did not disclose what exactly the two discussed.

"They discussed a wide array of topics,” Earnest said, “but this was mostly a social occasion.”
