So I would not take advice from a senator or an actor. A senator might have more reliable info than an actor but not necessarily. I studied physics at Penn State Univ. PA, USA. I know that a screen will only stop bugs that are larger than the holes in the screen and I know it's bad to lick a screen. (masks).

Here is some reporting by the Daily Mail that the Senator might be reffering to:

"A randomised study published by scientists at Copenhagen University, thought to be the best of its kind so far, found no statistical evidence that they offer any protection whatsoever. Reacting to the finding in a column in The Spectator today, Oxford University's Professor Carl Heneghan and Dr Tom Jefferson said there had been 'a troubling lack of robust evidence on face masks and Covid-19'.There have only been three 'real life' studies comparing mask-wearers to non-mask-wearers — one in Guinea-Bissau, one in India and the new Denmark study. All have shown masks to have no benefit in preventing the disease.But the experts added: 'Now we have properly rigorous scientific research we can rely on, the evidence shows wearing masks in the community does not significantly reduce the rates of infection."

So maybe your humor doesn't have a leg to stand on in the real world. Maybe it's "Robish"?
