Billy Long ended his brief tenure as IRS commissioner Friday, posting on X that President Donald Trump will nominate him to be ambassador to Iceland.

It was not immediately clear why Long was dismissed. His quick exit makes him the shortest-tenured IRS commissioner confirmed by the Senate since 1862.

Billy Long was a ridiculous character to put in the role of IRS commissioner, but despite his lack of qualifications, he appears to have put up a fight when it came to defending taxpayers' private data from immigration enforcement officials.
