The city says it plans to keep constant and tight security at Trump Tower in Midtown during the holidays. NY1's Dean Meminger filed the following report.

The NYPD says it is a reality: President-elect Donald Trump's home, Trump Tower, is a potential terror target and must be protected.  

"Officers assigned on observation posts, on elevated positions and on rooftops," said NYPD Chief of Department Carlos Gomez.

And that's 24 hours a day, seven days a week for at least the next two months, until Trump is sworn in as president and moves into the White House.

So for now, 56th street will be closed to traffic between Fifth and Madison avenues. Two lanes of Fifth Avenue in front of Trump Tower will be closed, too. And trucks will be banned on Fifth Avenue from 60th to 55th streets.

"It is an unprecedented challenge," said Mayor Bill de Blasio. "In the modern world, with the security dynamics we face today, we have never had a president of the United States who would be here on such a regular basis."

Hundreds of officers and traffic agents will be stationed on the blocks around Trump Tower, but it is the Secret Service that will be by Trump's side, responsible for protecting him. That agency says having the nation's largest police department as a partner brings a level of comfort.

"Throughout my career, I have traveled all over the world. I can think of no city better equipped, better prepared to deal with this challenge than New York," said David Beach, New York special agent in charge with the Secret Service.

At this point, the Secret Service says it is satisfied with the security and there are no immediate plans to change the building's glass facade. 

All residents of Trump Tower and visitors to the building can expect to be screened by Secret Service and NYPD officers every time they enter.

Protecting President-elect Donald Trump is definitely costing the city a lot of money, especially when it comes to overtime for the NYPD. And the city is looking to get reimbursed from the federal government.

"We are gong to be talking to senior members of the Obama administration about that," de Blasio said. "That will continue, as I said, into the Trump administration."

It remains to be seen what will happen in the area once Trump moves to Washington.
