Federal prosecutors are urging a judge to reject Hunter Biden's attempts to dismiss the gun charges against him, revealing that investigators found cocaine residue on the pouch he used to hold his gun. The prosecutors argue that the evidence against him is overwhelming and push back against Biden's claims that he is being singled out for political purposes. In addition to incriminating statements made by Biden about his drug use in his memoir, investigators found a white powdery substance on the leather pouch he used to store the gun, which was later determined to be cocaine. Biden has pleaded not guilty to charges of lying about his drug use on a form to buy a gun. His lawyers argue that he didn't break the law and that he has since stopped using drugs and turned his life around.

The gun charges could have been avoided with a plea deal last year, but the agreement fell apart, leading to the trial. Biden was indicted after a judge raised questions about the deal and he initially agreed to plead guilty to misdemeanor tax charges. His lawyers have urged the judge to dismiss the gun case, claiming he was selectively charged for political purposes. However, prosecutors argue that there is no evidence to support this allegation and that the charges are a result of Biden's own choices.

The trial comes as congressional Republicans continue to link Biden's business dealings to his father, President Joe Biden. Republicans are pursuing an impeachment inquiry into the president, claiming he was involved in an influence-peddling scheme with his son. However, no evidence has emerged to prove these claims. Meanwhile, negotiations between Hunter Biden's attorneys and House Republicans have halted plans to hold him in contempt of Congress for defying a congressional subpoena in their ongoing investigation.

Overall, Hunter Biden's legal troubles continue to overshadow his father's bid for a second term as president. The gun charges, along with the ongoing scrutiny of his business dealings, present significant challenges for the Biden family. The trial will determine whether Biden is found guilty of illegally possessing a firearm and making false statements, with potential consequences including a maximum sentence of 25 years in prison.
