Sept. 15 (UPI) -- The U.S. Supreme Court dealt another blow to President Donald Trump's plan to restrict voting by mail in a decision the president called "bad" for Republicans.
The high court ruled 7-2 on Monday, rejecting Trump's third bid to allow his executive order restricting mail-in voting to take effect. Justices Samuel Alito and Clarence Thomas dissented.
In a post on social media Tuesday morning, Trump called the United States' mail-in voting system a "Nation Destroying SCAM."
"Republicans just got another bad decision from the United States Supreme Court, one that the Court System took forever to give, and then blamed it, in part, on no time left to implement a solution to our totally CORRUPT and out of control Mail-In voting 'disaster,' which is a laughing stock all over the World, and where we are the only country that has to endure such a Nation Destroying SCAM," Trump posted.
The Trump administration filed an emergency application last week calling on the Supreme Court to block a lower court ruling that went against the voting restrictions. In its brief filed Monday, the Supreme Court said the administration's argument is "unlikely to succeed on the merits of its challenge to the District Court's preliminary injunction."
If Trump's plan took effect, it would have directed the U.S. Postal Service to withhold mail-in ballots in certain cases, adding requirements for verifying voter eligibility and tracking ballots.
Voting rights advocates have argued that these restrictions could disenfranchise large swaths of voters. They have also warned that implementing such restrictions so quickly before November's midterms would create additional challenges for voters and election administrators.
In Trump's post Tuesday morning, he also criticized the Supreme Court for its decision to block him from ending birthright citizenship in the United States.
Conservatives have a 6-3 majority on the Supreme Court and Trump has appointed three of the conservative justices: Brett Kavanaugh, Amy Coney Barrett and Neil Gorsuch.
