a month later returned for Christmas. On March 7, 2020, President Trump hosted Brazilian president Jair Bolsonaro for a working dinner, where the two leaders discussed the U.S.-led effort to oust Venezuelan president Nicolás Maduro, a future trade deal and peace for the Middle East. Also at the dinner was Bolsonaro's press secretary, , whose wife informed others on social media on March 11, 2020, that he had tested positive for COVID-19 after he had returned from the United States via Miami to Brazil. Others attending the dinner included Vice President Mike Pence, Ivanka Trump, and Jared Kushner. Security zone When President Trump was in residence as president, the Palm Beach region became a zone of temporary flight restrictions affecting flights and air operations severely within a 30 nautical mile (55.56 km) radius. Coast Guard and Secret Service secured the two waterway approaches, ocean and lake, and Secret Service cordoned off streets to Mar-a-Lago during the president's visits. The Coast Guard also attached an elite Maritime Safety and Security Team with unique capabilities that specialized in maritime security.

The Mar-a-Lago Club The primary business occupying the estate is the Mar-a-Lago Club, which opened in 1994 and operates as resort and hotel for dues-paying members, and rents out estate venues for private events.

Membership at the Mar-a-Lago Club required a $200,000 initiation fee. In 2012, reportedly in response to reduced demand following the Bernie Madoff scandal which affected many affluent Palm Beach residents, the fee was lowered to $100,000. The fee returned to $200,000 in January 2017 after Trump was elected president, with $14,000 annual dues. Overnight guests paid up to $2,000 a night. The membership list of Mar-a-Lago has long been shrouded in secrecy. The 2020 book The Grifter's Club had access to old membership records from the club, which confirmed that Jeffrey Epstein had been a member until 2007, and reveals that he was expelled "after Epstein harassed the daughter of a member", according to another
