While it is preliminary in nature.

The Delaware State Prosecutor’s Office is conducting a preliminary investigation into the sources of income of the son of U.S. President Hunter Biden, including in connection with his work in Ukraine, for possible tax violations. This was reported on Monday by The Wall Street Journal, citing sources close to the investigation.

As the newspaper notes, representatives of the prosecutor’s office have been actively sending requests to Hunter Biden’s former partners in recent weeks. We are talking, in particular, about the money received by the son of the U.S. president from the Ukrainian energy company Burisma Holdings in the mid-2010s, as well as the use of these funds to buy bond packages.

Hunter Biden was a member of the board of directors of Burisma in 2014-2015, receiving about $50,000 per month for mediation, consulting and lobbying services. Political opponents of the current U.S. president suggest that at this time the Biden family formed a personal interest in the situation in Ukraine and ties with the current authorities of the country.

The investigation is still preliminary. The collected testimony, if there are grounds, can be submitted to the federal grand jury, which decides on the possibility of bringing charges. However, at the moment such a possibility remains hypothetical; the newspaper does not report specific plans in this direction.
