Independent presidential candidate Robert F. Kennedy Jr. will remain on Colorado’s general election ballot after he suspended his campaign and endorsed Republican nominee Donald Trump, Kennedy’s campaign told Colorado election officials Tuesday.

“We are not withdrawing in Colorado,” Kennedy’s campaign told the Colorado Secretary of State’s Office, according to a spokesman. The message added that Kennedy “has encouraged all of his supporters to vote for him in CO!”

The former Democrat appeared Friday alongside Trump in Phoenix, where Kennedy announced he was backing the former president and would withdraw from the ballot in several states where his candidacy could swing the outcome. The Associated Press reported that it was already too late, however, for Kennedy to remove his name from ballots in Michigan, Nevada and Wisconsin.

The deadline to finalize Colorado’s ballot is Sept. 6. County clerks are scheduled to start mailing ballots to most state voters on Oct. 11.

Kennedy, an environmental attorney and nephew of former President John F. Kennedy, qualified for a line on the Colorado ballot as an unaffiliated candidate earlier this month after submitting more than the required number of petition signatures. The state’s Libertarian Party also attempted to designate Kennedy and his running mate, Nicole Shanahan, as its nominees, despite the party having already nominated another ticket — Chase Oliver and Mike ter Maat — at its national convention.

The Kennedy campaign didn’t respond to inquiries from Colorado Politics asking whether he intended to remain on the state’s ballot or would campaign in the state this fall after suspending his bid.

Kennedy is scheduled to speak at the Independent National Convention in Denver next month.

On Tuesday, Trump added Kennedy and former U.S. Rep. Tulsi Gabbard, another former Democrat, to his transition team. When he formally endorsed Trump last week, Kennedy said he hoped to join the Republican’s administration as a cabinet member.

While it was considered a key battleground state as recently as a decade ago, Colorado is ranked as solidly Democratic at the presidential level this year. President Joe Biden won Colorado’s electoral votes by more than 13 percentage points in 2020, marking the fourth time the Democratic nominee has carried the state.
