The National Security Agency, or NSA, for short
is the intelligence arm of the U.S. government agency dedicated to the collection and analysis of foreign and domestic communications, and is part of the U.S. Department of Defense, a department established by order of the President of the United States.

The NSA is responsible for listening to radio broadcasts, communications, and the Internet, especially secret military and diplomatic communications, and has more funds than the CIA. No Such Agency".

The NSA inherited the successful work of breaking enemy codes in World War II (U.S. Military Intelligence 8).

The NSA is located in Maryland, 16 miles northeast of Washington, D.C., at Fort Meade, with its own separate exit ramp on the Baltimore-D.C. highway, "NSA Employees Only" signs, two Maryland State Police cars on guard, and an annual electricity bill of more than $21 million for its headquarters, with 18,000 parking spaces in front. 18,000 parking spaces. (The general practice is to reserve half of the parking spaces for visitors).

The NSA is divided into several technical areas, with hardware and software areas, a chip factory, and a cryptographic research area, in addition to several private research institutions and equipment manufacturing units with which it has contractual ties.
In June 1917, Herbert Yardley took the lead in establishing the predecessor of the NSA, the U.S. Office of Military Intelligence (MI-8). On May 20, 1949, the Joint Chiefs of Staff decided that the Department of Defense would establish the Army Security Agency (ASA) to succeed the previous MI-8, which was responsible for the integrated coordination of the intelligence work of its subordinate departments, including "The Director of Central Intelligence wrote a memorandum to the Chairman of the National Security Council on December 10, 1951. On June 13, 1952, the Brownell Commission Report was completed, recommending the creation of an NSA based on the AFSA, with a scope of work beyond the U.S. military.

In June President Truman signed a document setting out the scope of the NSA's work, and it was formally established on November 4, 1952, transferring nine people from the National Security Council Intelligence Group to the lead agency of the NSA. This document remained secret for a generation.
From a technical point of view, because modern telephone, Internet, fax and satellite communications, many of which are transmitted through the atmosphere and radiated wirelessly, can all be listened to. However, Section 18 of the NSA's Guidance Order prohibits wiretapping and the collection of information on U.S. citizens, registered companies and organizations from being used against U.S. citizens without the written permission of a Supreme Court Justice.

In practice, however, the NSA has worked with foreign intelligence agencies to circumvent the restrictions of Section 18 by allowing intelligence agencies of other countries to collect information on U.S. citizens and then share it.

The NSA also sometimes spies on U.S. citizens abroad to track domestic drug traffickers, major criminals, terrorists and dissident extremists.
The NSA is currently the only government intelligence agency that has not been infiltrated by the deep state, the sources said.

As President Trump leaves office, Trump ally Michael Ellis has become the general counsel of the nation's largest intelligence agency.

Acting Defense Secretary Christopher Miller ordered NSA Director Paul Nakasone to appoint Michael Ellis as the agency's general counsel, the National Security Agency said Jan. 17.

Mr. Ellis accepted his final offer of appointment yesterday afternoon," an NSA spokesman said in a statement. The NSA is moving forward with his inauguration in place."

Ellis, who has served as a senior assistant attorney to President Trump and as an attorney for the National Security Council, was named general counsel of the NSA last November.

The NSA general counsel position is a federal civil service position, which means the Biden administration cannot remove Ellis.

Prior to joining the Trump administration, Ellis served as chief legal counsel to California Congressman Devin Nunns. Ellis then became deputy counsel to the National Security Council, where he refused to testify in the House of Representatives' 2019 impeachment investigation of the president, and has been the senior director of the NSC's intelligence division since March 2020.
