Kareem Abdul-Jabbar spoke at the Democratic National Convention on Thursday, and he didn't hold back any punches.

The Los Angeles Lakers legend spoke at the convention to introduce a film about an American Muslim named Captain Humayun Khan, who died in combat since the country's great tragedy on 9/11

As an American Muslim himself, it was important that he addressed presidential candidate Donald Trump, and his idea to register Muslim citizens and prevent them from entering the country. It's a policy proposal he likened to governmental tyranny.

Abdul-Jabbar also said Trump doesn't know the difference between him or Michael Jordan stirring cheers from the crowd.

Politics get ugly, and there is no question that Abdul-Jabbar stirred up a pot of controversy with his speech.
