None of the indictments are for speech. Free or otherwise.
Speech can be used as evidence to a committed crime which is typically what a conspiracy is.
So if a man goes into a bank and tells the teller, I have a gun, give me all your money...and subsequently robs the bank. The statement that he has a gun and wants the money is used as evidence against the crime of bank robbery. They will not be convicted of his speech.
The only thing worse then that is thinking that just because someone is running for president, they are above the law. If that is the case everyone could run for president and it would be like thunderdome for two years ahead of every election which of course is half the time.
You will have to more specific.
Again; none of the indictments are for something Trump said, however what Trump did say can and is being used against him in support of the actions he carried out.
Obviously you aren't thinking this up on your own...so who is telling you these obviously flawed legal theories? Which outlet? Fox? Gateway pundit? Alex Jones? Tucker?
If you could post a link to whoever is telling you to make these outrageous legal claims, I would be eager to read it.
