While young, the Department is the third largest cabinet agency by personnel, with nearly 250,000 employees. [...] The Committee recommends a total appropriation of $72,527,309,000 for the Department of Homeland Security for fiscal year 2020. Of this amount, $70,725,000,000 is for discretionary programs, including $190,000,000 for Coast Guard overseas contingency operations and $17,352,000,000 for the Disaster Relief Fund designated by the Congress as disaster relief pursuant to Public Law 112-25."
