What is the most likely reason that Dr. King refers to both the Constitution and the Declaration of Independence in his I Have a Dream speech?

Dr. King refers to both the Constitution and the Declaration of Independence in his "I Have a Dream" speech to emphasize the foundational principles of equality and justice that these documents represent. By invoking these texts, he highlights the hypocrisy of a nation that professes freedom and equality while perpetuating racial injustice. This connection serves to reinforce his demand for civil rights and to remind the audience of the unfulfilled promises made to all Americans, especially African Americans. Ultimately, it positions the Civil Rights Movement as a continuation of the American struggle for true democracy.
