Answer:
failure to investigate civil rights violations.
Step-by-step explanation:
Although Martin Luther King boldly criticized the attorney general and the Department of Justice for its failure to investigate civil rights violations, he wrote Kennedy in 1964 praising him for his efforts to pass the Civil Rights Act of 1964.
The relationship between the Attorney General Kennedy and the civil rights movement was tested when King and several hundred protesters were threatened by an angry mob outside of a Montgomery church, where King was holding a mass meeting in support of the Freedom Rides.
Kennedy opposed racial discrimination and U.S. involvement in the Vietnam War. He was an advocate for issues related to human rights and social justice and formed relationships with Martin Luther King Jr. and Cesar Chavez.
