In a brief order Friday evening, the justices summarily refused the unusual case Texas filed Monday against four swing states whose voters favored Biden.
"Texas has not demonstrated a judicially cognizable interest in the manner in which another State conducts its elections," the court wrote in its unsigned order.
No justice indicated any endorsement of Texas' arguments. Justices Samuel Alito and Clarence Thomas issued a statement saying they would have allowed Texas' to file its case under a rarely-used procedure for interstate disputes, but they said "would not grant other relief."
The decision brings an abrupt, unceremonious end to Trump's legal effort to essentially scrap the democratic process in order to preserve his presidency, a six-week-long crusade in which he has spread false conspiracies about voter fraud to drive up distrust of the U.S. election system. Trump dubbed the Supreme Court gambit "the big one" and had publicly pressed the justices to rule for him to "save America."
Texas's audacious legal move, lodged by its scandal-plagued attorney general Ken Paxton, won Trump's endorsement and the backing of 126 Republican members of the House, including GOP Leader Kevin McCarthy. However, the attempt also prompted an angry reaction from the targeted states and led many Democrats and some GOP officials to denounce the effort as a dangerous assault on the foundation of American democracy.
"Every American who cares about the rule of law should take comfort that the Supreme Court — including all three of President Trump's picks — closed the book on the nonsense," Sen. Ben Sasse (R-Neb.) tweeted Friday evening.
