Shiva Ayyadurai, the Massachusetts man who for years has made a widely-disputed claim that he invented e-mail, has formally declared his intention to run as a candidate for the United States Senate in 2018.

The Federal Elections Commission only recently published Ayyadurai’s statement of candidacy online. It has a filing date of March 17.

The Boston-area political neophyte announced his intention to run about a month ago on Twitter. He would be challenging incumbent Senator Elizabeth Warren, a Democrat.
