President Donald Trump has dismissed Billy Long as commissioner of the Internal Revenue Service barely eight weeks after the former Missouri congressman was sworn in on 16 June, according to reports first carried by the New York Times and later confirmed by Reuters and NBC News. Treasury Secretary Scott Bessent will assume the IRS post on an acting basis while the White House searches for a permanent successor, forcing him to juggle oversight of the tax agency with his existing Treasury portfolio. The temporary appointment makes Bessent the sixth person to run the IRS this year. People familiar with the matter told several outlets that Trump is expected to nominate Long for an ambassadorship in Iceland. No reason for the abrupt change was provided. Long’s brief tenure had drawn scrutiny over his limited tax-administration background and earlier support for abolishing the IRS. The shake-up comes amid a period of turbulence at the agency, which has endured repeated leadership changes and deep workforce reductions during Trump’s second term. Treasury and the White House have not announced a timetable for naming a permanent commissioner.
