WASHINGTON>> Hunter Biden was indicted Thursday on federal firearms charges, the latest step in a long-running investigation into the president’s son that puts the case on track toward a possible high-stakes trial as the 2024 election looms.

Biden is accused of lying about his drug use when he bought a firearm in October 2018, a period when he has acknowledged struggling with addiction to crack cocaine, according to the indictment filed in federal court in Delaware by a special counsel overseeing the case.The indictment comes weeks after the collapse of a plea deal that would have averted a criminal trial and weeks or months of distracting headlines for President Joe Biden.

The court fight may be an extended one: His defense attorney argued Hunter Biden didn’t violate the law and remains protected by an immunity provision that was part of the plea deal. The charges, meanwhile, are rarely filed as stand-alone counts and a recent appeals court decision called the law itself into question.

President Biden’s son also has been under investigation for his business dealings, and the special counsel has indicated that tax charges could be filed at some point in the future in Washington or in California, where he lives.

Political pressure has escalated as the House has opened an impeachment inquiry into the Democratic president, seeking to tie the elder Biden to his son’s businesses and divert attention from former President Donald Trump’s legal woes.

Over the years-long probe, federal prosecutors have not indicated Joe Biden is connected.

And so far, Republicans have unearthed no significant evidence of wrongdoing by the elder Biden. The White House maintains Joe Biden was not involved in his son’s business affairs.

The prosecutor who has long overseen the Hunter Biden investigation, Trump-appointed Delaware U.S. Attorney David Weiss, was elevated to special counsel last month, giving him broad authority to investigate and report his findings.

The three-count indictment says Hunter Biden lied on a form required for every gun purchase when he bought a .38 Colt Cobra Special at a Wilmington, Del., gun shop.

He’s charged with two counts of making false statements by checking a box falsely saying he was not addicted to drugs and giving it to the shop for their federally required records. A third count alleges he possessed the gun for about 11 days despite knowing he was a drug user.

The counts are punishable by up to 25 years in prison, upon conviction, a statement from Weiss and the Justice Department said.

Rep. James Comer, the lead Republican pursuing an impeachment inquiry into the president, called the indictment Thursday “a very small start.” But, he said in a statement, unless the Justice Department pursues the claims Republicans have put out regarding whether the president was involved in his son’s business dealings, “it will be clear President Biden’s DOJ is protecting Hunter Biden and the big guy.”

A felony gun charge against Hunter Biden, 53, previously was part of a plea deal that also included guilty pleas to misdemeanor tax charges, but the agreement imploded during a court hearing in July when a judge raised questions about its unusual provisions. The agreement would not have included a guilty plea on the gun charge but spared him formal prosecution if he stayed out of trouble for two years.
