@Jeanne I use an app called Free Download Manager to download videos, documents etc (I am yet to find something I cannot download with it). I have used it for years without problems and, so far, it has also managed to remain free of ads, yippee! I have attached a screenshot of it from the Google play store. This is for demonstration, I have never used it on a tablet or smartphone, only laptops. I downloaded Kamala Harris video and it worked so you should be able to do it without incident.
