The campaign claims that Murphy appropriated power that belongs to the New Jersey state legislature when he overhauled the state’s election law, alleging he violated both the Elections Clause and the Electors Clause of the U.S. Constitution. It also accuses Murphy of violating the 14th Amendment.

Justin Clark, Trump’s deputy campaign manager, wrote in an op-ed for The Wall Street Journal that New Jerseyans “who want to vote in person face a real threat that their ballots won’t be counted.”

Clark links to a 2016 investigation by the New Jersey outlet Ashbury Park Press which found 2,460 voters on the rolls who had been dead for at least five years, nearly 60 of whom had apparently cast votes after they died.

That same investigation, however, found that those votes were likely counted due to clerical errors rather than fraud, and no election outcomes were changed because of it.
