Final answer:
President Lyndon B. Johnson signed the Civil Rights Act of 1964 in the East Room, banning discrimination and becoming a key civil rights milestone.
Step-by-step explanation:
This seminal legislation, which originated with President John F. Kennedy and faced strong opposition including a Senate filibuster, was ultimately passed thanks to the strategic political efforts of President Johnson.
The Act, signed on July 2, 1964, at the White House, is a cornerstone of civil rights legislation that outlaws discrimination based on race, religion, national origin, and gender in public accommodations, housing, and employment. It also empowered the federal government to enforce these provisions.
