The Department of Homeland Security said on Wednesday that it will deploy 500 Immigration and Customs Enforcement officers to airports in New York on Thursday to assist Transportation Security Administration officers, as the partial government shutdown has reached 40 days.

ICE officers had already been deployed to at least 13 major airports, including New York’s LaGuardia Airport and John F. Kennedy International Airport, earlier this week, but the New York travel hubs will be getting additional support as thousands of TSA officers have called out sick due to the shutdown, according to NewsNation.
