In a since-deleted tweet, Mr Trump had said there would be a “big press conference” at the “Four Seasons” on Saturday morning local time.
Trump soon altered his statement, revealing that the press conference venue was not a Four Seasons hotel, but Four Seasons Total Landscaping, a suburban business between a crematorium and an adult book store on the outer edges of the city.
“Big press conference today in Philadelphia at Four Seasons Total Landscaping – 11.30am!” the president tweeted at 9.45am.
The hotel itself tweeted: “To clarify, President Trump’s press conference will NOT be held at Four Seasons Hotel Philadelphia.
“It will be held at Four Seasons Total Landscaping — no relation with the hotel.”
Four Seasons Total Landscaping, on State Road, Philadelphia, is situated next to Fantasy Island Adult Books and Delaware Valley Cremation Centre.
In a new post, Mr Trump himself later confirmed the conference would be held at the landscaping centre, but ultimately it was his lawyer Rudy Giuliani who spoke to reporters at the scene rather than the US president.
The statement from Mr Giuliani came after it was announced that Joe Biden was projected to win the US election and reiterated Mr Trump’s calls for legal proceedings against supposed election fraud.
Many on social media compared the scene to classic political comedy The Thick Of It.
Simon Blackwell, who helped write the hit show with Armando Iannucci, connected it with another of the pair’s political comedies, tweeting: “Veep still available to stream and on DVD.”
Comedy writer Zack Bornstein tweeted: “I could write jokes for 800 years and I’d never think of something funnier than Trump booking the Four Seasons for his big presser, and it turning out to be the Four Seasons Total Landscaping parking lot between a dildo store and a crematorium.
“Also the twist that they announced Biden won DURING the conference, and Rudy asked which network called it, and the reporters said ‘All of them’.”
Another comedian, Christine Nangle posted a video in which she pretended to take the call booking the space outside the landscaper.
“No we don’t have a podium, why would we have a podium? We have a rototiller,” said Ms Nangle in character. “I know that’s not the same thing I’m just trying to match your energy.”
Another Twitter user @TechnicallyRon, posted: “Remember when a bunch of lawyers tried to book the four seasons for a press conference to defend a president but accidentally booked a garden centre.
“Whenever I need cheering up, I’m just going to remember this.”
