(CNN) President Donald Trump, a native New Yorker, has now declared himself a Florida resident, according to court documents.

The President changed his permanent residence to his Mar-a-Lago Club in Palm Beach, Florida, in late September, and first lady Melania Trump followed suit in October, in forms filed with the Palm Beach County Circuit Court.

In a series of tweets Thursday night, Trump said he was leaving New York because he's been "treated very badly" by politicians in the Empire State.

"1600 Pennsylvania Avenue, the White House, is the place I have come to love and will stay for, hopefully, another 5 years as we MAKE AMERICA GREAT AGAIN, but my family and I will be making Palm Beach, Florida, our Permanent Residence," Trump tweeted.

"I cherish New York, and the people of New York, and always will, but 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. I hated having to make this decision, but in the end it will be best for all concerned. As President, I will always be there to help New York and the great people of New York. It will always have a special place in my heart!"
