Federal Appropriations Update • We believe that ICE continues to face budgetary pressures, and the outcome and timing of ongoing federal budget discussions in Congress remain uncertain. • Since October 1, 2023, the U.S. Department of Homeland Security and ICE have been funded under a short-term Continuing Resolution, which has been extended three times and is currently set to expire on March 22, 2024. • In February 2024, a group U.S. Senators released a proposed Supplemental Appropriations Bill that would have provided funding for 50,000 ICE detention beds and increased the annual funding for Alternatives to Detention programs to approximately $1.3 billion, from the current funding level of $440 million. • The proposed Supplemental Appropriations Bill did not pass in the full U.S. Senate. Subsequently, a bipartisan group of U.S. House of Representatives lawmakers have introduced a $66 billion foreign aid and border package. • If Congress is unable to reach agreement on an appropriations package prior nd to March 22 , the federal government could continue to be funded under a continuing resolution or face the prospect of a government shutdown. 15
