WASHINGTON (AP) — Homeland Security Secretary Markwayne Mullin on Friday warned that state officials could lose funding or face investigations if they fail to go along with President Donald Trump’s election security demands, part of the Republican president’s longstanding attempt to undermine Americans’ confidence in the vote.

Experts said the threats — issued just months before midterm elections that will determine control of Congress — were likely hollow because Trump’s voting initiatives have been stalled by judges and the Constitution gives states control over how elections are run.
