The head of USA Gymnastics has stepped down under pressure following a sex abuse scandal that has rocked the organization.

FOX's Gurnal Scott reports:

Steve Penny had been with USA Gymnastics for 18 years, the last 12 as its president, overseeing much of the most successful run for the ladies of the sport over the last four Olympics. Today he stepped aside in the wake of allegations against former team doctor Larry Nassar, who is accused of sexually abusing female teen aged gymnasts.

In a statement, Penny says his resignation is "solely to support the best interests of USA Gymnastics at this time." Still some of the more than 70 women suing the organization say Penny's departure is not enough to bring about change.

An organization-wide review of current policies is ongoing.
