A new report finds businesses around Trump Tower have been negatively impacted by the new security measures around the Midtown building.

The survey of 50 small businesses by City Comptroller Scott Stringer's office found the measures to protect the President-elect have caused sales to plummet this holiday season.

Nearly half of participants said they're severely impacted and two-thirds predicted lower revenues. 

Stringer says shops have seen less foot traffic, delayed deliveries and late trash pickups.

"We have to listen to some of their concerns about how to create more robust foot traffic capability there," Stringer said. "We certainly should look at any kind of grant program, or easing of some restrictions where appropriate, so that they can make it and there ought to be some federal assistance, I believe for the small businesses."

12 percent of surveyed businesses said they would consider closing, laying off employees or changing locations.
