The Civil Rights
Is difficult to overstate the importance of Civil Rights Act
Powers given to enforce the act were initially weak, but were supplemented during later years. Congress asserted its authority to legislate under several different parts of the United States Constitution, principally its power to regulate interstate commerce under Article One, its duty to guarantee all citizens equal protection of the laws under the 14th Amendment and its duty to protect voting rights under the 15th Amendment. The Act was signed into law by President Lyndol B. Johnson on July 2, 1964 at the White House.
