Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

It is legal to peaceably petition the government for a redress of grievances.
It is illegal to disrupt the Congress and demonstrate in the Congressional buildings.

Yet another moronic comment from you. Having the right to petition the government does not mean you can disrupt official proceedings and refuse to leave when ordered to by the police. It's the content of speech that's protected, you can't go to jail for saying Biden sucks...you can go to jail for disrupting official proceedings and trespassing. You're pretending the right to free speech gives one the right to conduct that speech however they want, and that is again...an incredibly stupid thing to suggest.

Good job, but our rights don’t include standing up and screaming during official proceedings. It’s more that the government can’t arrest him for writing an op-ed or Twitter feed criticizing Biden.
