A far-left Antifa group that has plans for an anti-police demonstration in New York City on Friday urged their followers to “f*** s*** up on J31 all day long.” That prompted a withering but also hilarious reply from Donald Trump Jr., who fired back on Twitter, “Too late … The New York’s mayor has been doing that for years now.”

The group, known as Decolonize This Place, plans to protest at 5 p.m. on Friday at Grand Central Station not only against police in the subway but also to demand riders be allowed to ride the trains for free. The Daily Mail noted, “Photos shows glue being poured over subway turnstiles, doors being held open with zip ties and vandalism on the walls of stations.”

In the video posted by the group on Twitter, a masked man states what the group wants followers to do: “We encourage you to link up with your friends, your family, and think of the ways you can move in affinity to build, and f**k s**t up on J31 all day long. The mood for J31 is simple: F**k your $2.75. No cops in the MTA, free transit, no harassment period, and full accessibility.”

A New York Police Department told The Daily Mail the department is “aware of the demonstration and will have an adequate police presence in place.” The Police Benevolent Association of New York City responded to Antifa by asserting, “New Yorkers should pay close attention: this is true endgame of the anti-police movement, an end of all policing & destruction of public order. Our members have spent their careers – and in some cases given their lives – to bring public safety back to NYC. We can’t go backwards.”

Last week, 500 new officers were sworn in to protect the New York City transit, the Long Island Railroad and Metro-North, prompting Decolonize This Place to post on Facebook:

This is a declaration of war against our communities. That money should not be invested in the harassing and brutalizing of Black and brown folks. It should go toward making the MTA free, well maintained, and accessible to all.”

Decolonize This Place released a “communique” which read:
