Which legislation created a new cabinet-level department on November 25, 2002?

The legislation that created a new cabinet-level department on November 25, 2002, is the Homeland Security Act of 2002. This act was a significant response to the terrorist attacks of September 11, 2001, and aimed to consolidate various agencies and functions related to homeland security into a single department to improve the nation's ability to protect against and respond to threats.

The establishment of the Department of Homeland Security (DHS) marked a pivotal shift in how the federal government approached national security, focusing on better coordination among diverse agencies involved in areas such as immigration enforcement, border security, cybersecurity, and disaster response. The act had a profound impact on various policies and initiatives pertaining to the safety and security of U.S. citizens.

The other pieces of legislation mentioned focus on different aspects of national security and law enforcement but do not pertain to the creation of a new cabinet-level department. The USA Patriot Act, for instance, was designed to enhance law enforcement's ability to prevent terrorism by expanding surveillance capabilities but did not create DHS. The Intelligence Reform Act focused on reforming the intelligence community without establishing a new department, while the Anti-Terrorism Act primarily dealt with measures to combat terrorism rather than reorganizing federal structures.
