The initial claim of the post is that former President Trump faked and staged a visit to a McDonalds in Feasterville, Pa in order to gain publicity.
There are several factors that support this claim although some of them lack validity. According to an article published by NewsWeek, and several posts on the social media site Reddit, it is said that the customers President Trump allegedly served were in fact pre-selected campaign donors. It is important to note that outside of videos on social media these specific claims cannot be verified.
According to an article by The Washington Post, "The restaurant was closed to the public during Trump’s visit, and the motorists whom Trump served were screened by the U.S. Secret Service and positioned before his arrival." This supports the idea that the stunt was much more planned than the Trump campaign initially let on. "No one ordered food. Instead, the attendees received whatever Trump gave them." This claim was further supported by NBC news, who said this, "The customers who went through the drive thru were pre-selected by the franchise and the local Trump campaign team, according to a person familiar with the event."
In summary, it seems that the initial claim of the post is largely true, and that large parts of Trumps service were exaggerated or genuinely disinformation.
