An Arab-American activist who attended an outreach session at the White House complex in April had his Chicago home raided by the FBI last week and appears to be a focus of an unfolding federal terrorism-support investigation.

Hatem Abudayyeh, who serves as executive director of the Arab-American Action Network, took part in a meeting for Arab-American leaders held in the Eisenhower Executive Office Building on April 22, according to appointment data posted on the White House website.
