President-elect Donald Trump doubled down on his attack on Broadway sensation 'Hamilton' on Sunday morning.

The drama began at the Friday night performance as soon as Vice President-elect Mike Pence walked into the Richard Rodgers Theatre with his nephew and daughter.

A mixture of boos and cheers rang out from the crowd as Pence slipped into his prime orchestra seat.

When the show ended, Pence was asked by a cast member to hear a prepared speech after the curtain call from the multiracial and multicultural cast, saying it is concerned about the Trump administration.

'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,' said Brandon Victor Dixon, who plays Aaron Burr, the nation's third vice president, as his fellow actors joined hands.

'We truly hope that this show has inspired you to uphold our American values and to work on behalf of all of us.'

President-elect Donald Trump doubled down on his attack on Broadway sensation 'Hamilton' on Sunday morning.

The unusual address quickly went viral — and Trump wasn't happy.

On Saturday, just five minutes after ending his day of meeting with potential cabinet members, Trump tweeted that Pence had been 'harassed' by the 'Hamilton' cast.

In another tweet, he said: '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!'

He posted another such message Saturday evening, but then deleted it.

It came as Trump and Pence supporters held rallies near the theater in New York to protest the 'harassment' of the vice president-elect.

Then, early Sunday morning, Trump again took to Twitter to demand the cast and producers 'immediately apologize to Mike Pence for their terrible behavior.'

This time, Trump added a dig at the critically acclaimed show, which is sold out until September 2017, saying he has heard it's 'highly overrated.'

But the cast of Hamilton has received support from celebrities, including Chrissy Teigen who noted that Trump was attacking the show in a bid to distract Americans from his decision to settle his Trump University fraud lawsuit for $25million on Friday.

'Look who wants a f****** safe space now. The very thing him and his supporters make fun of as liberal political correctness. God, what a POS,' she wrote on Twitter.

'Donald knows very well what he is doing. He knows the Hamilton speech was NBD. He knows the tweet will fire both sides up to distract from the 25 million dollar settlement of yesterday.'

She added: 'Most conniving human on planet earth.'

Dixon responded to Trump on Twitter saying that 'conversation is not harassment sir' and added that he appreciated Pence stopping to listen.

Trump had posted a tweet Saturday evening similar to his earlier ones but later deleted it. Staffers did not respond to an email asking why.

His day had been full of meetings with potential cabinet members, including an awkward face-to-face with Mitt Romney, and what Trump called successful meetings with retired Gen. James Mattis, Betsy DeVos and Michelle Rhee who could head the board of education, and others.

On Sunday morning, while awaiting a second day of important meetings, this time with officials including New Jersey Governor Chris Christie and former New York City Mayor Rudy Giuliani, Trump took to Twitter again to resume his complaints about the 'Hamilton cast.'

'The cast and producers of Hamilton, which I hear is highly overrated, should immediately apologize to Mike Pence for their terrible behavior,' he tweeted.

But Pence says that he wasn't offended by what was said and even said he'd told his children that the boos were what 'freedom sounds like.'

In an interview with Chris Wallace on Sunday, Pence said that he had enjoyed the show and highly recommended it.

'First off, my daughter and I and her cousins really enjoyed the show Hamilton it's just an incredible production and incredibly talented people and it was a real joy to be there,' Pence said.

'When we arrived, we heard a few boos and we heard some cheers and I nudged my kids and reminded them that's what freedom sounds like.

'But at the end I did hear what was said from the stage and I can tell you, I wasn't offended by what was said, I'll leave to others whether that was the appropriate venue to say it.'

Asked if he wanted or expected an apology, Pence said: 'As I said, I would leave that to others whether that was the appropriate venue for that.

'I will tell you Chris, if you haven't seen the show, go to see it. It is a great, great show and I'm a real history buff. My daughter and I and her cousins really enjoyed it.'

Pence added: 'I do want to say that the basic element is the center of that message is one I want to address, I know this is a very disappointing time for people that did not see their candidate win in this national election.

'I know this is a very anxious time for some people, I just want to reassure people that what President-elect Donald Trump said on election night, he absolutely meant from the bottom of his heart.

'He is preparing to be the president of all of the people of the United States of America and to watch him bringing together people of diverse views, bringing together people that differed with him strongly, seeing him talk to leaders around the world.

'I just want to reassure every American that in the days ahead I'm very confident that they're going to see president-elect Donald Trump be a president for all the people and we embrace that principle and we're going to work hard to make that principle every day that we serve.

Trump's press pool was called a 'lid', or finish, for the day at 7.27pm. At 7.32pm he sent out the tweet

Early on Saturday, Trump tweeted out twice about the incident, in which Pence was booed by the Hamilton audience before being formally addressed by the cast

Reaction to the debacle was mixed, with some calling Dixon's speech 'disrespectful' and threatening to boycott the show and others saying it was an important message that needed to be delivered.

The musical is by Lin-Manuel Miranda, who wrote the story, music and lyrics.

It stresses the orphan, immigrant roots of first U.S. Treasury Secretary Alexander Hamilton and has a terrifically varied score, ranging from pop ballads to gospel to sexy R&B.

It has been cheered for reclaiming the nation's founding story with a multicultural cast.

Miranda, in a tweet, said he was 'proud' of Dixon and the 'Hamilton' cast 'for leading with love,' before reminding people that everyone is welcome at the theater.

Miranda had been a big booster for the failed presidential campaign of Trump's opponent, Democrat Hillary Clinton, including performing at an all-star fundraiser for her last month.

The cast also put on a special 'Hamilton' show at a Clinton fundraiser last summer.

The person playing Alexander Hamilton that Pence saw was Javier Munoz, an openly gay actor.

Pence supported numerous efforts to ban gay marriage as governor of Indiana and opposed unfettered federal funding for HIV and AIDS treatment.

He has also long been known for his strong, anti-LGBT views - including the belief that electric shock therapy worked in making gay men into straight.

After the show on Friday, a crowd gathered outside the theater to chant 'F*** Mike Pence.'

But on Saturday, a group of Trump supporters performed a 'flash mob' outside the Richard Rogers Theater holding pro-Trump signs, American flags and chanted 'USA'.

A Trump supporter reportedly interrupted Saturday evening's performance of Hamilton.

The man, who was seated in the balcony, yelled 'We won! You Lost! Get over it! F*** you!' during the number 'Dear Theodosia,' according to BroadwayWorld.

Another person at the show told the website that the Trump supporter had become enraged by the line: 'Immigrants, we get the job done.'

The altercation reportedly lasted through two numbers before the disruptive man was removed from the auditorium following a tussle with security.

Trump's feud with the cast of a Broadway is the latest indication that he will remain unable to rein in his Twitter habit.

He had told 60 Minutes in his first interview since being elected that he intended to restrain himself.
