Has Trump learned his lesson about violating the 1st Amendment? Or will he keep revoking the credentials of journalists who question him?

Trump never learns.. He will keep make bµll$hits...

He makes his own rules and does as he pleases

It doesn't really violate the first amendment. He's still allowed to write about whatever he wants.

It's an invitation into a building; does that mean every journalist who's denied entry has their rights

being violated?

He did not violate the first ammendment. He tried to make reporters take turns, each asking one respectful question that had not already been asked before. It is child's play. He got one in trouble for breaking the rules and interfering with the mic bearer. This question is funny coming from people in favor of eroding every constitutional right we have, including perverting the meaning of free press. Costa can state his wrong opinions in his publications. That's press. You are confusing printing press with pressuring someone, which borders on harrassment.

It was illegal but not a 1A violation. Yet.

He didnt ,Acosta is not a reporter just a drama queen

He didn't violate the first amendment. He literally can't. Read it, genius.

How did he violate anyone’s first amendment? Please do tell. Bexuse if you believe it then why didn’t you go after obama who had the FBI get phone and email records for AP reporters and a Fox News referee.

Trump is stupid. Do you really think he has learned anything?

You can't teach an old dog new tricks.
