The U.S. Supreme Court appears poised to keep Donald Trump on this year’s presidential election ballot, as the justices weigh a historic clash over Colorado voter efforts to disqualify him over his role in the Jan. 6 Capitol riot.

Justice Elena Kagan said the Colorado decision had national implications. "Why should a single state have the ability to make this determination not only for their own citizens but for the rest of the nation?”
