I heard of laws against interfering with a Federal official in the performance of his duties, and I believe a similar law was used to prosecute Scientologists who stole government information. It is doubtful, however, that this Administration has the "stones" to prosecute anyone, knowing that the Left-Wing MSM will surely condemn them for attempting to suppress free speech.
This isn't free speech, it's treason. These subversives need to be rounded up and their groups shut down.
