Former President Donald J. Trump asked the U.S. Supreme Court on Wednesday to keep him on the primary ballot in Colorado, appealing an explosive ruling from the state Supreme Court declaring him ineligible based on his efforts to overturn the 2020 election that culminated in the Jan. 6, 2021, attack on the Capitol.
The move adds to the growing pressure on the U.S. Supreme Court to act, given the number of challenges to Mr. Trump’s eligibility and the need for a nationwide resolution of the question as the primaries approach.
