Francis Suarez, Miami Mayor, Is Running for President: What to Know

In early 2021, he criticized Mr. DeSantis for forbidding local leaders to enforce mask mandates as Covid-19 cases surged, telling CBS News that he had tried unsuccessfully to reach Mr. DeSantis and persuade him to let officials “institute things that we think are common-sense, that we think are backed up by science, that we can demonstrate are backed up by science.”

And two years earlier, he co-wrote a New York Times opinion essay with Ban Ki-moon, the former secretary general of the United Nations, emphasizing the damage climate change was already doing in Miami. “There isn’t a single aspect of our daily lives that isn’t affected by climate change,” he and Mr. Ban wrote.

He opposed Trump in 2020, but defends him now.

When other Republicans have changed their minds about Mr. Trump, it has generally been to oppose him after previously supporting him, à la Chris Christie. Mr. Suarez has gone in the opposite direction: Though he did not vote for Mr. Trump in 2020, he has said he will in 2024 if Mr. Trump is the Republican nominee.

He told Fox News this month that he was motivated by “a fear of Joe Biden’s America.”

“It’s an America where the poor get poorer, it’s an America where America gets weaker, and it’s an America where the possibility of China being the lone superpower is something that frightens me to no end,” he said.

“What has changed and what has happened is we’ve gotten a taste of what a dysfunctional government can do to destroy our country in a short period of time,” Mr. Suarez added, “and if you take that out into the future, it is incredibly scary.”

When Mr. Trump was indicted in New York this year, Mr. Suarez told The Miami Herald that he saw the Manhattan district attorney’s decision to pursue the case as “a slippery slope.” After Mr. Trump’s second indictment this month, he went further, saying in the Fox News interview that it “feels un-American.”
