Thousands of protesters gathered around and even inside Trump Tower ahead of the President Trump's arrival Monday night.

Many demonstrators rallied outside Trump's Midtown home, pointing signs toward the building with the message that he is not welcome in the city.

"No Trump, no KKK, no fascist USA!" some chanted.

People had gathered about two blocks away from Trump Tower for a rally there in advance of a march towards the building. They were later held about a block away on 57th St. and 5th Ave.

The president's motorcade pulled up to Trump Tower around 9 p.m. while avoiding the protesters, who chanted "Shame, shame, shame'' while awaiting him.

The protesters carried signs with such messages as "impeach'' and "stop the hate, stop the lies.''

Nearby, an inflatable, rat-like caricature of Trump, seen below, stood by The Plaza hotel.

City Council Speaker Melissa Mark-Viverito, a Democrat, was among the protesters.

A group of about two dozen supporters of the president said "God bless President Trump'' as they rallied in support of him. They were kept separate from the anti-Trump demonstrators.

"Donald Trump won. Trump is president. That's it," a Trump supporter said. "No matter how much you fight it, you're not going to win."

"They'll call me a Nazi, but do you know that you're acting like a Nazi by telling me to get off the street?'' Shaun Jackson, a tax attorney, said at the pro-Trump rally.

With supporters and anti-Trump demonstrators penned across the sidewalk, both sides yelled at each other, "Go home!''

A block south of Trump Tower, police officers with bullhorns confronted protesters pressing against and straining the barricades, telling the demonstrators to step back.

Police have stationed sand-filled sanitation trucks as barriers around the building and layers of metal police barricades around the main entrance.

After Trump was elected president, security around the tower ramped up dramatically. Barricades and checkpoints were manned by scores of uniformed police officers. The security precautions have been lessened somewhat in Trump's absence but still have inconvenienced residents and business owners in the highly-trafficked area.

Trump, who lived in his Midtown skyscraper before he was inaugurated, said Friday that he had stayed away because he realized the impact of the street closings and other aspects of a presidential visit.

"I would love to go to my home in Trump Tower, but it's very, very disruptive to do,'' he said.

Onlookers who did see the motorcade Monday night greeted it with cellphone cameras and a few obscene gestures.

The rally, which was not violent, began to thin out in the evening before Trump's arrival. It was in part honoring Heather Heyer, who officials said was killed when an Ohio man plowed a car into her and a crowd of people protesting a white nationalist rally in Charlottesville, Virginia on Saturday.

A second anti-Trump protest gathered at the New York Public Library at 42nd St. and marched toward Columbus Circle, with hundreds there also denouncing the president.

One image on social media, seen below, showed that two protesters were inside Trump Tower, despite a very heavy police presence outside, and pressed signs to a window.

"He is a dangerous, dangerous man," said one demonstrator outside Trump Tower.

"If this was a Muslim or a black crowd on Saturday, driving into a crowd and being that vile, then they would have had a military operation, they would have had a different response," another said. "He would have been talking about terrorism."

"One person should not be dead right now for speaking up for what's right," one man said at the Trump Tower rally.

Many people at the rally expressed outrage, specifically, at the Queens-native's remarks after the Charlottesville protest.

"We condemn in the strongest possible terms this egregious display of hatred, bigotry, and violence on many sides, on many sides," Trump said in a press conference Saturday afternoon. "This has been going on for a long time in our country. Not Donald Trump, not Barack Obama — this has been going on for a long, long time."

"I don't know what rhetoric they'd be referring to," a supporter of the president said Monday outside Trump Tower. "I've seen no issue whatsoever with anything he's said, nothing white supremacist."

But some of the white nationalists cited Trump's 2016 election victory as validation for their beliefs, and Trump's critics pointed to the president's racially tinged rhetoric as exploiting the nation's festering racial tension.

The Rev. Jesse Jackson noted that Trump for years publicly questioned President Obama's citizenship.

Many officials also criticized the president for claiming that hatred has been "on many sides."

Monday afternoon, Trump directly condemned the hate groups responsible for the deadly violence in Virginia.

He spoke after he discussed the race-fueled violence with the FBI and Attorney General Jeff Sessions.

"Racism is evil, and those who cause violence in its name are criminals and thugs, including the KKK, Neo-Nazis, white supremacists, and other hate groups that are repugnant to everything we hold dear as Americans," Trump said Monday in Washington.
