House Minority Leader Hakeem Jeffries (D-NY) will not support any funding for the Department of Homeland Security without a deal on the conduct of federal officials, a new line in the sand for congressional Democrats that increases the likelihood of a partial government shutdown later this month.

Jeffries told the Washington Examiner he is a “hard no” on a full-year bill that keeps DHS funding flat, viewed by Republicans as a “fallback” in the event negotiations over immigration enforcement fall through.
