The Maryland Aviation Administration released a statement saying ICE informed the state that additional Department of Homeland Security personnel, including Enforcement Removal Operations (ERO) and Homeland Security Investigations (HSI), were being deployed to BWI-Marshall starting Saturday afternoon.

“MAA was advised by the Transportation Security Administration (TSA) that ICE personnel will be working to assist TSA security checkpoints at BWI-Marshall, similar to their roles during recent deployments at airports across the country,” MAA said in a statement.

The deployment comes as travelers waited multiple hours in security lines at BWI-Marshall that wrapped around four times and extended outside the concourse by Saturday evening. The airport urges travelers to arrive at least four hours before their flight’s departure time.
