President-elect Donald Trump, who is just two months away from his inauguration, woke up Saturday morning with a pressing concern on his mind.

What got him worked up was the fact that Mike Pence was booed by the audience during a performance of “Hamilton” on Friday, and that the cast took time to deliver a personal message to the Vice President-elect after the show.

Our wonderful future V.P. Mike Pence was harassed last night at the theater by the cast of Hamilton, cameras blazing.This should not happen! — Donald J. Trump (@realDonaldTrump) November 19, 2016

The Theater must always be a safe and special place.The cast of Hamilton was very rude last night to a very good man, Mike Pence. Apologize! — Donald J. Trump (@realDonaldTrump) November 19, 2016

Kellyanne Conway, Trump’s campaign manager, also tweeted that Pence shouldn’t have been booed when he entered the theater to watch the show.

This is so true. And @mike_pence deserves respect and a peaceful night out with his nephew and daughter. #yourvicepresident https://t.co/h38lcamWLg — Kellyanne Conway (@KellyannePolls) November 19, 2016

After the last curtain call, actor Brandon Dixon addressed Pence respectfully from the stage and asked him if he would stick around for a special message.

“We, sir, we are the diverse America, who are alarmed and anxious that your new administration will not protect us, our planet, our children, our parents or defend us and uphold our inalienable rights.

“But we truly hope that this show has inspired you to uphold our American values and to work on behalf of all of us.”

Dixon, who plays Aaron Burr in the show, responded to Trump on Twitter and actually praised Pence for listening.

@realDonaldTrump conversation is not harassment sir. And I appreciate @mike_pence for stopping to listen. — Brandon Victor Dixon (@BrandonVDixon) November 19, 2016

Trump was still upset about it Saturday night, tweeting that the cast was "very rude." The tweet was then deleted.

It’s not unusual for senior political leaders to be booed in public places, including presidents. But Trump seems to have a personal philosophy of letting no criticism go unnoticed.

“One of the things you should do in terms of success: If somebody hits you, you’ve got to hit ’em back five times harder than they ever thought possible,” he said in 2012.

“You’ve got to get even. Get even. And the reason, the reason you do, is so important... The reason you do, you have to do it, because if they do that to you, you have to leave a telltale sign that they just can’t take advantage of you.”

Pence said he was not offended by the remarks in an interview on “Fox News Sunday.”

.@mike_pence: I really enjoyed watching Hamilton. It was a real joy to be there. I heard a few boos. I wasn't offended by what was said. — FoxNewsSunday (@FoxNewsSunday) November 20, 2016
