5. The purpose of the cartoon was to create sympathy for the African Americans, considering AJ despised them.
6. The intended audience was anyone who did not agree with AJ's veto. The cartoonist's purpose was to raise awareness to this issue.

8. AJ was literally kicking out the Bureau with his veto, as illustrated in the cartoon. Racism is still largely prevalent in the government. Congress and the president disagreed on this issue. Newspaper headlines all around the country read, "<em>SIDE WITH CONGRESS, SIDE WITH THE NEGROES. SIDE WITH THE PRESIDENT, SIDE WITH THE WHITE MAN</em>."
Hope this helped.

I hope this helps somehow ;)
