Was trump a part of the us government?

While the right cries about twitter and facebook blocking free speech, that they have the right to do, trump was trying to censor Jimmy Kimmel by reaching out to ABC.
And, he tried to censor Chrissy Teigan by reaching out to twitter.🤔
These we are aware of. How many others did he try to silence?
He is what the first amendment is supposed to protect us from.
