Free speech, you don’t have to like it but in the USA of my birth you can say what you please. Look at the news reports about Trump, his children, his wife, concerning Russia, Ukraine, China, N Korea, “His Hotels”, which really are just Licensed to use the Trump name to bring in customers and BLING BLING it up.
No idiot. You cannot go on the public airwaves and say something you know to be false about another person. That’s against the law.
