President Barack Obama and First Lady Michelle landed in Chicago Saturday night and en route on Air Force One Deputy National Security Advisor Ben Rhodes said he was not overly concerned over the arrests of three suspects over an alleged "terrorism plot."
Rhodes said he was not aware that Obama knew anything about the arrests and said "protests and security disruptions" are common at summits.
"We're very confident in the ability of Chicago, together with the United States government, to have a very successful event over the course of the next two days. If these more serious allegations are true, then I think it was effective work in making sure that they couldn't pose any additional threat to public security. But I'll have to wait -- what additional information comes out before getting into the specifics of this case."
