Sen. Andy Kim (D-NJ) was among those pepper-sprayed by Immigration and Customs Enforcement officers outside a detention facility in New Jersey on Monday during demonstrations against the Trump administration’s deportation agenda.

The first-term senator engaged with protesters and federal agents during a demonstration against the conditions at the Newark-based facility that Democrats say is home to an ongoing hunger strike by detainees. Kim and other New Jersey Democrats attempted to gain access to conduct an oversight visit but were rebuffed.
