Six months of shaky decisions and turmoil came to a head for the U.S. Olympic Committee on Wednesday when its acting CEO said she would step down, bringing more chaos to an organization that was humiliated when Chicago's bid to host the 2016 Games fell flat.

Stephanie Streeter said that she would not seek the USOC's CEO job on a permanent basis, and that she would leave in the next five months.

The decision came just five days after Chicago's humbling first-round exit in a vote by International Olympic Committee members, who ultimately picked Rio de Janeiro. It also happened on the same day leaders of America's Olympic sports organizations said "No" in a 40-0 vote to this question on a survey they conducted: "Do you believe the acting CEO has the ability to be an effective leader of the Olympic movement?"

The United States contributes more money to the Olympics than any other nation, yet the USOC is rife with infighting and turnover, perceived internationally as arrogant, and populated with leaders who are having trouble turning things around.

"I'm incredibly saddened by the developments, which I lay largely at the feet of the USOC, which has clearly lost its way," NBC Universal Sports and Olympics chairman Dick Ebersol said. "I don't believe there will be another Olympics in the U.S. until the USOC really gets its act together."

USOC Chairman Larry Probst conceded that turning around the group's international reputation is not a one- or two-year project. "I'm talking 10, 15, 20 years," he said.

The USOC will hire a national recruiting firm by the end of the month to search for Streeter's replacement. The next CEO will be the third in the span of about a year.
