Obama to answer questions at Facebook HQ

US President Barack Obama will answer questions submitted via Facebook during an appearance at the social network's California headquarters later this month, the White House said Tuesday.

In an announcement on its own Facebook page, the White House said Obama will sit down with Facebook founder Mark Zuckerberg and chief operating officer Sheryl Sandberg for a "town hall" event at Facebook's Palo Alto offices on April 20.

The "Facebook Live" event will be streamed live on Facebook starting at 1:45 pm Pacific time (2045 GMT).

The White House said Facebook will select questions on the economy and innovation for Obama to answer during the event.

Questions can be submitted through WhiteHouse.gov/facebooktownhall or the Facebook event page.

Obama, who announced on Monday through Facebook and Twitter that he would seek reelection in 2012, met with the 26-year-old Zuckerberg and other Silicon Valley technology leaders during a visit to California in February.
