What is national emergency​

The National Emergencies Act is a United States federal law passed to end all previous national emergencies and to formalize the emergency powers of the President. The Act empowers the President to activate special powers during a crisis but imposes certain procedural formalities when invoking such powers

Explanation:

Presidents have long had broad discretion to declare national emergencies and can tap into an array of emergency powers when they do.

While those emergency powers aren't spelled out in the Constitution, legal scholars say the president is entitled to them under the broadly defined "executive power." Abraham Lincoln used the power to suspend habeas corpus during the Civil War, while Franklin Roosevelt used it to order the internment of more than 100,000 Japanese-Americans during World War II.

Congress set out to limit the power after the Watergate scandal with the National Emergencies Act of 1976. The act scaled back the provisions of federal law that granted emergency authority to the president — then about 470 — and was intended to give lawmakers a way to check presidential power.
