How did John F. Kennedy respond to Governor George Wallace's threat to block the University of Alabama in Tuscaloosa?

In June 1963, when Governor George Wallace threatened to block the integration of the University of Alabama, President John F. Kennedy responded by asserting the federal government's commitment to enforcing civil rights. He delivered a televised address where he emphasized the necessity of desegregation and the importance of upholding the law. Kennedy ultimately sent federal troops to ensure that African American students could enroll at the university, demonstrating his administration's stance against segregation and support for civil rights.
