Robert F. Kennedy Jr. asked the Supreme Court on Monday to keep his name on New York’s presidential ballot, even though he suspended his campaign in August and backed former President Donald Trump.

In an emergency appeal, Kennedy argued that New York voters who signed petitions supporting him “have a constitutional right to have Kennedy placed on the ballot – and to vote for him, whether he is campaigning for their vote or not.”

In August, Kennedy suspended his presidential campaign and endorsed Trump, pledging to remove his name from the ballot in a handful of battleground states yet encouraging supporters in non-competitive states traditionally won by Republicans or Democrats to vote for him.
