Hunter Biden agreed with the Justice Department on Tuesday to plead guilty to two misdemeanor tax charges and accept terms that would allow him to avoid prosecution on a separate gun charge, a big step toward ending a long-running and politically explosive investigation into the finances, drug use and international business dealings of President Biden’s troubled son.
Under a deal hashed out with a federal prosecutor who was appointed by President Donald J. Trump, Mr. Biden agreed to plead guilty to misdemeanor counts of failing to pay his 2017 and 2018 taxes on time and be sentenced to probation.
