Free speech is one thing. But you can’t lie to the court as an officer of the court. You can’t commit a crime while claiming free speech. You can’t slander or libel someone (although there is a sliding scale for public figures) and call it free speech.
But isn’t it ironic that Trump would gladly incarcerate those who excercise free speech in their criticisms of him because other countries do it.
BTW, do you want Biden cognitively tested by Trump’s former WH doctor, Dr. Johnson?
