The freakish incident happened as the USA president addressed a campaign rally crowd in Montana.
About an hour into Trump's speech, a woman can be seen walking over, speaking to the plaid-shirted man briefly and then taking his place. He was quickly appointed a "cultural icon", a "voice of the people", and - for some people, at least - a potential candidate for the 2020 election.
On Thursday, Tyler Linfesty stood behind Trump, in full view of many cameras, and listened to the president speak on various subjects, including tax reform and the media. He told the Daily Beast that the woman told him, "I'm going to take your place now" before making him leave. "But whenever I agreed with him, you know, I clapped", Linfesty said.
'When people signed up to go to the rally, their names were placed into a draw and I was chosen.
Linfesty said he didn't go to the event with the intention of making a scene, but couldn't help himself while listening to Trump.
Linfesty was later interviewed on CNN Tonight with Don Lemon, saying his reactions were natural and not acted out, and that he would have given them if anybody said such ridiculous things to him. "So when I got back there I knew I was going to be really genuine and give my actual reaction to the things he said so when I disagreed with him, you could tell I disagreed but when I did agree with him I clapped as well". "She just said to me, 'I'm going to replace you'". So whenever I disagreed with him, you could tell that I disagreed. "And when he said something I thought was good or I agreed with, I applauded". "His two friends also attended Boys State with me earlier in the summer!"
"Some Secret Service guys took me backstage and told me to wait".
"I didn't really have a plan", Linfesty told the Gazette.
It's no wonder that Linfesty wasn't too bothered by the removal, though, considering that he openly supports the Democrats (and can even be seen wearing a social democrats sticker while standing behind the president).
According to the Gazette, one of its reporters saw Trump staffers reviewing a photo of Linfesty and the Democratic Socialist of America rose emblem he wore before removing Linfesty and his friends.
So, whether you're a Trump supporter or not, it seems that this latest rally from the president had a little bit of something for everyone.
The crowd behind Trump at his rallies usually seems carefully selected, since they know those will be the people visible in video of the event, but it seems that their extreme vetting wasn't quite thorough enough this time around.
