President Trump has asked the US Supreme Court to allow the administration to implement an executive order issued by him in March. If implemented, the executive order would give the Department of Homeland Security (DHS) and the US Postal Service (USPS) new powers and responsibilities connected to mail-in ballots. States would be required to mail ballots to voters using only envelopes that are approved by the USPS, including “a unique Intelligent Mail barcode.” In June, 23 states sued to block the executive order, arguing that the order violates the Constitution’s separation of powers, Elections and Electors Clauses, along with the Tenth Amendment’s anti-commandeering doctrine. Other lawsuits against the executive order are pending, including one filed by the Democratic National Committee in April.
