Blatter returns to FIFA headquarters amid Swiss investigation

FIFA president Sepp Blatter, who only three days ago faced charges of criminal mismanagement and misappropriation from Swiss investigators, is due to speak with staff members Monday.

The 79-year-old is back at work in Zurich, and is scheduled to make his address at 4 p.m. local time (10 a.m. ET). The meeting, according to the Associated Press, is said to be a "regular gathering" that happens every month.

Blatter risks a possible suspension from FIFA's ethics committee, which could force the president to cede his position earlier than thought.

He had already announced he would resign and allow a new election to take place in February following a barrage of corruption allegations.
