This really is treason. Take a look at the article.
"Less than a week after Stefan Halper was outed as the FBI informant who infiltrated the Trump campaign, public records reveal that the 73-year-old Oxford University professor and former U.S. government official was paid handsomely by the Obama administration starting in 2012 for various research projects.
A longtime CIA and FBI asset who once reportedly ran a spy-operation on the Jimmy Carter administration, Halper was enlisted by the FBI to spy on several Trump campaign aides during the 2016 U.S. election. Meanwhile, a search of public records reveals that between 2012 and 2018, Halper received a total of $1,058,161 from the Department of Defense."
