The partial shutdown of the Department of Homeland Security (DHS) is set to surpass previous records if Congress does not resolve its disagreement over funding. The House passed a bill to fund the entire department for eight weeks through May 22, but it is unlikely to pass in the Senate due to a lack of support from some Democrats. The stalemate has resulted in shortages of resources and long lines at airport security checkpoints. President Donald Trump has taken steps to alleviate the strain, including allowing federal workers to receive pay during the shutdown.
