Who is the audience for John Lewis speech?

The administration of John F. Kennedy

Explanation:

John Lewis was the head of the Student Nonviolent Coordinating Committee. Becoming a chairman of the organization was also brought by his experienced of being mobbed by a white man when he was younger. In order to address racial discrimination and his full support of the Civil Rights bill, he made a speech which was addressed to the administration of John F. Kennedy (the President of that time). The speech was delivered during the "March on Washington."

Some revisions were made before he could deliver it because it sounded too inflammatory.

Thus, this explains the answer.
