Department of Homeland Security (Project Noah)

The United States Department of Homeland Security (DHS) is a cabinet department of the United States federal government with responsibilities in public security, roughly comparable to the interior or home ministries of other countries. Its stated missions involve anti-terrorism, border security, immigration and customs, cyber security, and disaster prevention and management. It was created in response to the September 11, 2001 attacks in the United States.

The U.S. Coast Guard is attached to the DHS during peacetime but maybe transferred to the Department of Defense during times of war as part of the United States Navy.

Prior to the outbreak, the Immigrations and Customs Enforcement (ICE) were known to be rounding up illegal immigrants and deporting them back to their countries as part of President Donald Trump's anti-illegal immigrant campaign.
