Hunter Biden's lawyers say prosecutors are inappropriately trying to insert “politically-charged” allegations about his foreign business dealings into the upcoming federal tax trial against the president's son. Special counsel David Weiss' team told the judge last week that they plan to call to the witness stand a business associate of Hunter Biden's to testify about an arrangement with a Romanian businessman who was trying to “influence U.S. government policy” during Joe Biden’s term as vice president. Hunter Biden's lawyers responded in court papers filed Sunday that such matters are irrelevant in the case headed for trial next month in Los Angeles over at least $1.4 million in taxes he owed between 2016 and 2019.
