Trump Signed An Order To Reshape How Elections In The Us Are Run. Is It Constitutional?

With the stroke of his pen, President Donald Trump restructured the way Americans can register to vote and when they can cast their ballots. Or did he?

After the president signed his executive order Tuesday calling for broad election changes, such as proof of citizenship for voter registration and an Election Day return deadline for mailed ballots, election officials, state attorneys general and legal experts said it would face legal challenges for encroaching on state powers outlined in the U.S. Constitution .

The order is "unlawful," Colorado Democratic Secretary of State Jena Griswold said in a statement.

"This cannot be done through executive action," said David Becker, a former U.S. Justice Department attorney who leads the nonprofit Center for Election Innovation and Research.

New Jersey Attorney General Matt Platkin said he expects his and other states will challenge the executive order, just as they have several other of Trump's actions. He said he's never seen a president threaten the integrity of state election rules like Trump did through his order.
