The GOP lawmaker, who later won re-election in spite of the controversy, has endorsed Tim Pawlenty's bid for the 2012 Republican presidential nomination.
Wilson shouted "You Lie!" at Obama during the president's speech on the House floor in September 2009, after Obama had assured the assembled lawmakers that the health care bill he was then seeking to get approved did not extend health coverage to illegal immigrants. Wilson's outburst prompted criticism from both Republicans and Democrats for disrespecting the president. He later apologized.
The GOP lawmaker will co-chair Pawlenty's campaign in South Carolina.
