The former president changed his primary residence from New York to Florida in late 2019. At the time, Trump said he would "always" cherish New York but felt mistreated by local politicians.

"Unfortunately, despite the fact that I pay millions of dollars in city, state and local taxes each year, I have been treated very badly by the political leaders of both the city and state. Few have been treated worse," Trump tweeted at the time.
