As I recall from all that I've read on the subject he was responsible for those acts being shepherded through Congress. It was his critics that these acts were intended to silence. (But I've been wrong before, heck, I voted for a democrat once.)
Definitely the Sedition Act was intended to silence Adams’ critics, but I don’t know whether he was involved in getting Congress to pass the bill. Interesting omission in the law—it wasn’t a crime to criticize the Vice President, since the Vice President at the time was Thomas Jefferson.
