U.S. President Barack Obama plans to answer questions from Hispanic voters in an online roundtable discussion as part of a push to re-energize the support of groups that backed him during the last election.

The event Wednesday is expected to focus on jobs, immigration, and other issues important to the Hispanic community.

Questions will be posed by readers of several websites, including Yahoo, MSN Latino, and AOL Latino/Huffington Post Latino Voice. It will be streamed live in English with Spanish translation on the White House website.

Mr. Obama has in recent months been trying to maintain or win back support from the nation's 50 million Hispanics, whose votes he will need to win re-election in 2012. Some recent surveys have shown a drop in his approval rating among the group.

The online discussion is the second time this week Mr. Obama has addressed questions from an online audience. Monday, the president answered questions submitted on the social networking site LinkedIn, as part of a three-day, five-city campaign tour.
