A person has been arrested and charged with threatening to kill the children of Ajit Pai, the head of the United States Federal Communications Commission (FCC), according to a court document.

The person identified as Markara Man made the threat in emails sent to Pai, one of the senior officials in President Donald Trump's administration, because he was angry that the FCC had repealed net neutrality, the affidavit filed in connection with the case by a law enforcement in a Virginia court said.
