This claim is false as there is no available information that former President Barack Obama committed treason. Treason means helping enemies of the U.S. or making war against it, and nothing Obama did meets that definition. President Donald Trump has claimed Obama spied on his 2016 campaign, but has never shown real evidence. Experts and U.S. intelligence officials say these claims are false. Investigations, including a bipartisan Senate report, found Russia interfered in 2016 but found no crimes by Obama.
