Federal prosecutors in 2022 are wrapped up the fourth year of their investigation into Hunter Biden for possible tax and foreign lobbying violations, false statements and more.

Hunter Biden has been under federal investigation since 2018.

The probe was predicated, in part, by suspicious activity reports (SARs) regarding suspicious foreign transactions. Those SARs, according to sources familiar with the investigation, involved funds from "China and other foreign nations."

Fox News first reported the existence of some type of investigation involving Hunter Biden in October 2020, ahead of the last presidential election. It became known then that the FBI had subpoenaed the laptop purportedly belonging to Hunter Biden in the course of an existing money laundering investigation.
