Multiple states, including Pennsylvania and Nevada, are pushing back against claims made by the Trump administration and the Department of Homeland Security (DHS) regarding the registration of thousands of noncitizens to vote. Pennsylvania officials are demanding evidence from the Trump administration after DHS suggested that over 14,000 noncitizens might be registered in the state. The reliability of the data supporting these claims is being questioned, with California officials explicitly challenging the DHS. As concerns mount across the U.S. regarding noncitizen voting, states are urging the federal government to clarify its assertions and provide substantiating evidence.
