President Donald Trump is putting a hold on $18 billion in funding for New York City rail projects because of the government shutdown.

The White House budget director, Russ Vought, said on a post on X that the step was taken due to the Republican administration’s belief the money was based on unconstitutional diversity, equity and inclusion principles.

The suspension of funds is likely meant to target Senate Democratic leader Chuck Schumer of New York, whom the White House is blaming for the shutdown.
