New York City will start painting “Black Lives Matter” on Fifth Avenue directly in front of Trump Tower on Thursday, picking up a delayed project that President Trump blasted as a “symbol of hate.”

City workers began closing the street early Thursday ahead of the work. Mayor Bill de Blasio is expected to take part in the effort at some point in the afternoon, sources tell NBC New York. A police official said that the street could be closed for a couple of days to do the work.

The original announcement drew furious condemnation from the president.
