The Doctored Video
So far I’ve only found the doctored video on Facebook. I’ll look for other sources in case it gets removed. At the time I’m posting this, the video can be viewed at this link if you have a Facebook account — but possibly also if you don’t. I tested the link while logged out of Facebook. If took multiple tries but with some persistence I was finally able to see it.
The True Video
Here are two views of the actual, un-manipulated video. First, from C-SPAN, is the brief 2-minute portion of Pelosi’s press conference that had been doctored.
Second, from PBS, is the full press conference held on May 20, 2020. The portion that was doctored starts at about 17½ minutes into the video.
