Long Island College Hospital remained open past its original scheduled closing date of Sunday, and medical workers and elected officials marked the occasion with a loud protest.
Workers gathered opposite of the hospital's entrance to call on Governor Andrew Cuomo to help keep the facility open.
LICH was set to close on Sunday, according to the closure plan approved by the state, but a state supreme court has kept a temporary restraining order in place to keep the facility open, until legal arguments are heard on Wednesday.
Some city leaders joined workers in the plea for political intervention.
"Mr. Governor, don't let real estate industry drive decisions of public health care in our state. We expect from you to do better," said Rep. Nydia Velazquez.
"The Brooklyn delegation to the New York Senate, Assembly, this is at your doorsteps. You have to make it happen, to preserve health care in our borough," said Brooklyn Borough President Marty Markowitz.
SUNY Downstate officials are looking to sell the 155-year-old facility, saying the hospital loses $15 million a month.
Opponents say losing the facility would have dangerous consequences for Cobble Hill and surrounding neighborhoods.
