The Justice Department is investigating Hunter Biden for foreign lobbying violations related to his overseas business dealings — likely in places such as China, Ukraine, and Kazakhstan — in addition to scrutinizing his taxes, according to a new report.

Delaware U.S. Attorney David Weiss is known to be leading a federal investigation into President Joe Biden’s adult son, who denies any wrongdoing, and the New York Times reported Wednesday that the investigation, which began as “a tax inquiry” during the Obama administration, then “widened” in 2018 to encompass “possible criminal violations of tax laws, as well as foreign lobbying and money laundering rules, according to the people familiar with the inquiry.”
