The Trump administration is asking Washington state to set aside any ballots received from more than 400 people it suspects registered to vote without U.S. citizenship. The Justice Department says the people have voted 1,500 times. This request is part of a broader effort to identify noncitizen voters, even though such cases are rare. California has challenged a similar request. Washington Secretary of State Steve Hobbs is reviewing the demand. Previous investigations into noncitizen voting have found far fewer instances than the Trump administration has claimed. In Nevada, a probe found zero noncitizen voters despite allegations of 1,500.
