American Muslims hold largest annual event in Chicago

CHICAGO -- The largest Muslim gathering in the U.S. is taking place in Chicago this weekend.

The annual convention of the Islamic Society of North America will feature several guest speakers, including Khizr and Ghazala Khan, who made national headlines by criticizing Donald Trump during the Democratic National Convention and Olympic bronze medalist Ibtihaj Muhammad.

They are set to speak twice at the convention. The Khans are Gold Star parents who lost their son while he was serving in Iraq. The couple got into a heated exchange with Donald Trump, when Khizr Khan spoke against Trump's Muslim immigration policy.

This convention is the largest of its kind in North America with speakers, seminars and products catered to the Muslim community. The idea is to bring more understanding and acceptance of the Muslim faith.

"ISNA is one of the most inclusive Muslim organizations in America. We have 48 percent female speakers this year I am very happy to say. That is something that is unprecedented among American Muslim organizations, and God willing next year we will have an even greater percentage percentage," said Hazem Vata of the Islamic Society of North America.

The theme for this year's convention is "Navigating Challenges, Seizing Opportunities." The group is promoting the teachings of Islam.

Homeland Security Secretary Jeh Johnson will address the conference Saturday night.
