The anti-Trump Republicans who are backing Harris' 2024 campaign

The big picture: In the home stretch of the narrowly divided race, the Harris-Walz campaign is ramping up its effort to attract Republican-leaning and undecided voters.

• Harris has said she'd appoint a Republican to her cabinet should she win in November.

Here are other former GOP officials who have endorsed the Harris-Walz ticket.

Former Michigan Rep. Fred Upton

The latest: Ex-Rep. Fred Upton, who voted to impeach Trump after the Jan. 6 Capitol riot, endorsed Harris with just under two weeks until Election Day, telling The Detroit News the former president is "totally unhinged."

• Upton told the outlet that he has already cast his ballot for Harris — his first time voting for a Democrat for president.
• "I don't have any qualms," he said. "I've been thinking about it for a while. Trump's not changed his colors."

Flashback: Upton announced his retirement in 2022 after more than three decades in Congress.

Former Vice President Dick Cheney

Former Vice President Dick Cheney, who once supported the former president, said he would vote for Harris, warning in a statement that he believed Trump "can never be trusted with power again."

• "In our nation's 248-year history, there has never been an individual who is a greater threat to our republic than Donald Trump," he said in a statement in September.
• The former vice president publicly changed his tune on Trump after the Jan. 6 attack on the U.S. Capitol.

Former Rep. Liz Cheney

Cheney (R-Wyo.) is famously one of the most outspoken anti-Trump Republicans. She has campaigned alongside Harris in October.

• She has repeatedly called for fellow Republicans disillusioned with Trump to back the Democratic ticket.
• "If people are uncertain, if people are thinking, 'Well, you know, I'm a conservative, I don't know that I can support Vice President Harris,' I would say, 'I don't know if anybody is more conservative than I am,'" Cheney said at an event this week. "I understand the most conservative value there is: to defend the Constitution."

Former Illinois Rep. Adam Kinzinger

The ex-congressman spoke at the Democratic National Convention in August, where he said the GOP has "switched its allegiance from the principles that gave it purpose to a man whose only purpose is itself."

• He told GOP voters to "vote for our bedrock values and vote for Kamala Harris."

The intrigue: He told Deadline last month he would "certainly" accept a cabinet post under Harris if offered one.

Former Arizona Sen. Jeff Flake

Flake, who served in Congress for close to two decades, said he would support the Democratic ticket earlier this week, citing his experience working with Walz in the House and Harris in the Senate.

• "I would encourage all Republicans who feel this way to do the same," he said in a post to X.

What he's saying: In a recent appearance on ABC's "This Week," Flake said he can't endorse a candidate who "tries to use the powers of the presidency to overturn" an election without mentioning Trump by name.

Former Georgia Lt. Gov. Geoff Duncan

Duncan, who opposed Trump's efforts to overturn the 2020 election, said at the DNC that Republicans who opted to vote for Harris were patriots.

• In May, he endorsed President Biden (before the president bowed out of the 2024 race), labeling Trump "a criminal defendant without a moral compass."

Ex-Trump White House officials endorse Harris

Former White House Communications Director Anthony Scaramucci and Press Secretary Stephanie Grisham have joined other members of the former administration's staff choosing not to back him in 2024.

• Scaramucci, speaking to MSNBC the night of the first debate between Harris and Trump, said "She [Harris] is the person dedicated to service — he's the person that's dedicated to self-service."
• Grisham spoke at the DNC. She told the crowd, "Kamala Harris tells the truth. She respects the American people and she has my vote."

Cassidy Hutchinson, a former Trump aide who delivered key testimony to the House Jan. 6 committee, endorsed Harris Wednesday, saying she's "really, really proud" to vote for the Democratic ticket.

• "Donald Trump and JD Vance cannot be trusted with the Constitution," she said on MSNBC. "They cannot be trusted to uphold our rule of law, and they can't be trusted to enact responsible policy."

Zoom out: Other former Trump administration and Republican officials, like former Vice President Mike Pence, have refused to endorse Trump but have stopped short of endorsing the Democratic ticket.

• The Harris campaign released an ad Thursday titled "Unstable Threat" featuring words of Trump's former allies, including Pence, deeming him unfit to serve.
