Delaney Hall, a privately operated detention center under contract with ICE, has been the site of turmoil during President Donald Trump’s immigration crackdown. Rob Menendez, a North Jersey Democrat, said in a video on X that he was showing up for an unannounced oversight visit to Delaney Hall. “This tragedy is another painful reminder of why Delaney Hall should be closed.” Delaney Hall, a gray, two-story building in an industrial area of Newark, has been a key part of that infrastructure. Menendez said on Monday that another individual who had been in custody at Delaney Hall died just weeks ago at University Hospital after a possible seizure.
