A federal judge has halted a plan nationwide that affects USPS mail ballot rules. The Trump administration is seeking Supreme Court intervention to revive the plan, citing potential harm from voter fraud.

The administration argues that the federal government would be seriously harmed if the plan is not put into effect. California and other states have warned of chaos if the Supreme Court allows the plan to stand.

Further details on the plan and the court case are available from the source, which has reported on the developments and the arguments presented by the parties involved.
