Denver ? Lloyd Ward quit Saturday as CEO of the U.S Olympic Committee, capping three months of turmoil that began with a conflict-of-interest investigation and led to the resignations of six other top officials.

“In the hope that we can shift the focus back to the athletes and the ideals of the Olympic movement, I have decided to resign,” Ward said in a statement issued by the USOC.

An interim CEO is expected to be chosen next week to work alongside an interim president. The group’s executive committee will start figuring out how to select a permanent replacement in the coming month.

The USOC is a powerful force in the Olympic movement, with its athletes winning the most medals and American sponsors and TV networks providing the most money for the International Olympic Committee. But turf battles among paid staffers and volunteers within the 123-member board of directors have made the USOC dysfunctional over the years.

Still, the latest run of turmoil is sticky even by USOC standards.

Ward has been under fire since he was accused of trying to steer Olympic business to a company with ties to his brother. No deal was made, but after an ethics investigation, Ward was reprimanded and stripped of a $184,000 bonus.

Since then, a top sponsor has threatened to pull out of a $10 million endorsement deal, Congress stepped in, and ethics compliance officer Pat Rodgers was among the half-dozen members who quit.
