A federal grand jury in April 2022 returned a four-count indictment that charged Jason Fong with attempting to provide material support to two foreign terrorist organizations – Hay'at Tahrir al-Sham (HTS) and Hamas. Fong allegedly attempted in the spring of 2020 to provide to HTS tactical, combat, and weapons training material – as well as information regarding the making of chemical weapons and improvised explosive devices. It was also further alleged that in May 2020, Fong attempted to fundraise for Hamas. It was further alleged that at the time he committed these offenses, Fong knew that each organization had been designated a foreign terrorist organization by the United States government.
