The lead prosecutor in the case against President Joe Biden’s son Hunter says he is willing to testify publicly this fall, setting up a clash with House Republicans who have demanded he come in soon for a closed-door interview. In a two-page letter to Rep. Jim Jordan on Monday, the Justice Department offered to make U.S. Attorney David Weiss of Delaware available before the House Judiciary Committee for a public hearing after the August break as Republicans continue to escalate their ongoing investigation into his handling of the probe into Hunter Biden.
