The Democratic president and the Republican governor are at odds over scores of issues, including climate change, which experts blame for Florida's increasingly wet, windy and intense hurricanes.

More than 100 people died and nearly 400,000 homes and businesses remained without power in Florida on Tuesday, five days after Hurricane Ian crashed across the state. On Monday, Biden visited Puerto Rico, a U.S. territory battered by Hurricane Fiona last month.

Biden will survey Florida's badly damaged Fort Myers by helicopter, before meeting with residents and disaster-relief officials, as well as DeSantis, according to the White House.

Biden has been in regular communication with DeSantis during the crisis and the federal government picked up a significant share of the initial disaster relief. Last week, Biden said his relationship with DeSantis is "irrelevant" but "very fine."

When Biden visited Florida in July after a condominium complex collapsed and killed nearly 100 people, he said, "we're letting the nation know we can cooperate when it's really important," as he and DeSantis sat shoulder to shoulder.

On climate change, Biden has made reducing carbon emissions a focus of his presidency, while DeSantis backed funding to harden Florida's defenses against flooding but also opposed some previous disaster-relief aid and pushed pension funds not to consider environmental impact when they invest.

Before Hurricane Ian hit, Biden had planned a rally in the political battleground state last week. Then, Democratic officials expected Biden to attack DeSantis' approach, which has included shunning COVID-19 lockdowns, mocking Biden's age and abilities, penalizing Walt Disney World Resort for opposing state laws limiting discussion of LGBTQ issues in schools and flying Venezuelan immigrants from Texas to Martha's Vineyard.
