Please provide an example of the US Congress scientifically investigating anything.
It’s political theater, meant to provide sound bites for media and fundraising efforts.
I’m all for investigating vaccine efficacy and safety, but Congress is not the body to perform such investigations. And I mean both the House and Senate, not just one or the other.
I don’t need to provide anything. Congress didn’t get their special powers to investigate things for no reason and whether you like it or not, they have that right.
If there’s nothing wrong with the vaccines you have nothing to fear.
