Secret Service agents guarded the front of the building as the NYPD worked to remove the truck, reports New York Daily News.

Police were able to identify the owner of the truck, according to CBS. It reportedly had out-of-state license plates that did not match the identification number.

It is unclear if President Trump's 10-year-old son was in school on Monday.

He and his mother, first lady Melania Trump, have been living in their Manhattan home at Trump Tower, while the president moved to Washington D.C. after taking office.
