President Donald Trump's administration is threatening to withhold some federal funding from states that don't make changes to voting practices and is warning state election officials that they face arrest if they don't remove noncitizens from voter rolls.

Letters to states and grant application details are the latest in a line of actions by Trump's administration to shape details of running elections that have long been the job of states.

Courts have largely rejected the administration's previous efforts, which reflect untrue claims about widespread voting fraud and come less than four months ahead of crucial midterm elections where Democrats seek to take control of one or both chambers of Congress and check Trump's power.
