Lawmakers and the White House offered no signs of compromise Sunday in their battle over oversight of federal immigration officers that has led to a pause in funding for the Department of Homeland Security.

A partial government shutdown began Saturday after congressional Democrats and President Donald Trump’s team failed to reach a deal on legislation to fund the department through September. Democrats are demanding changes to how immigration operations are conducted after the fatal shootings of U.S. citizens Alex Pretti and Renee Good by federal officers in Minneapolis last month.

Congress is on recess until Feb. 23, and both sides appear dug into their positions. The impasse affects agencies such as the Transportation Security Administration, the Federal Emergency Management Agency, U.S. Coast Guard, the Secret Service, U.S. Immigration and Customs Enforcement, and U.S. Customs and Border Protection.
