Just watched Monkey Werx sitrep for today. At the end he mentions the Trump/Davos video going around. I have seen multiple ones going around but I want to point out what I have noticed. The 3+ min one is definitely from 2018 as everyone keeps stating. The 19+ min one is interesting as I noticed in the first portion Trump's exit fom the helo he is escorted by 2 SS all the way to the row of cars almost as if they are holding his elbow. At about 12 min into this video you can clearly see Trump's exit from the helo is cmpletely different in that he is by himself and SS are standing back (I circled Trump in this exit). This 19+ min video is 2 different times Trump has been Davos. Monkey Werx said the video is from 2018. I don't know which version he watched but I'm sure he would've caught the different exits from the helos if he had seen the longer version. I am in no way saying the second part of the longer version is from 3/1/21 but it is not from 2018.
there is also a video from last year. it is filmed from a different angle but it looks like the video you posted at the bottom. if you go to YouTube and search trump davos it will come up from the AP. hope that helps.
