U.S. President Joe Biden while spending the weekend in Rehoboth Beach Delaware, went for a bike ride down the Gordons Pond bike lane along with his son Hunter Biden Saturday. Biden did not respond to reporters' questions about his preparation for a debate against presidential rival Donald Trump or when asked if he had a response to Israeli Prime Minister Benjamin Netanyahu’s statement on Saturday that said Israel’s demands for ending the war against Hamas have not changed. Biden's son Hunter is headed to trial on federal gun charges in a case brought by his father’s Justice Department. The trial is set to open Monday in Delaware with jury selection. The case isn't about Hunter Biden’s business dealings, which have been the focus of a lengthy federal investigation and an impeachment inquiry into the Democratic president by congressional Republicans. Prosecutors say Hunter Biden bought the gun illegally in October 2018 because he falsely swore on a federal form that he wasn't a drug user. His lawyers say he never fired the gun and that it ended up dumped in a trash can.
