President Barack Obama had a rare private lunch Tuesday with a visitor to the White House: fellow Nobel Peace Prize winner Elie Wiesel.

The pair dined together in the Private Dining Room at noon, and the event was closed to press.

Wiesel won the Nobel Peace Prize in 1986, largely for his Holocaust memoir, "Night," but also for his ensuing work on behalf of peace. Obama won the prize in 2009.

The president has seen Wiesel twice in the past year: In June, Obama asked Wiesel to accompany him on a visit to the Buchenwald concentration camp in Germany. In February of this year, Wiesel was honored at the White House for his work promoting human rights.
