Justices’ ruling comes after lower courts had blocked president’s election order ahead of November midterms

The US supreme court sided with Donald Trump on Monday in his effort to crack down on mail-in voting, though it remains unclear if his administration can take action ahead of the midterm elections in November.

Justices on the court voted 6-3 along ideological lines to lift an injunction from June that a judge in Massachusetts placed on an executive order issued by the president. But a second injunction remains in place and the ruling leaves room for legal challenges.
