KEY POINTS

  • About 100 guests partied -- all without masks, one partygoer said. 
  • One reveler insisted the party was on the roof; another saw action both inside and outside
  • The power couple stayed about an hour before heading out. 

Donald Trump Jr. and his girlfriend showed up Saturday night at a private bash in the Hamptons, another partygoer told The New York Post's Page Six. 

Trump and Kimberly Guilfoyle, a former Fox News host, joined roughly 100 other revelers -- all maskless, the source told Page Six . Joe Farell, a Hamptons builder, hosted the gala at his home in Bridgehampton, where Trump and Guilfoyle bought a house last year.

The partygoer claimed the party appeared “as if COVID had never happened.” 

An insider close to the president's oldest son, however, told Page Six that the couple stayed for about an hour at the party, which was held on the roof.  The partygoer claimed guests mingled both inside and outside. 

Trump’s partying came at the same time as the coronavirus spiked in dozens of states, especially in Texas, Florida, California and Arizona. Of more than 10 million cases worldwide, half have been in the United States and Europe, the BBC reported.

The U.S. has reported roughly 2.5 million coronavirus cases and more than 125,000 deaths related to COVID-19.
