The Wounded Warrior Project (WWP) announced Monday the appointment of retired Major Gen. Charlie Fletcher as interim chief operating officer (COO).

Fletcher, who has worked more than three decades in various miliary capacities in addition to senior-level management roles, will be the senior-most member of the Wounded Warriors team, based in Jacksonville, Fla.

"Charlie's impressive background and experience in both the military and private sector makes him uniquely positioned to lead our organization during this transition," WWP Board Chairman Anthony Odierno said in a statement. "I am confident in his ability to work alongside the Board and the leadership team to fulfill our mission of honoring and empowering Wounded Warriors."

The temporary installation comes nearly a month after the organization terminated CEO Steven Nardizzi and COO Al Giordano for exhibiting poor discretion in financial management.

A CBS News investigation, as well as an internal audit by the group's board of directors, found nearly half of the hundreds of millions of funraised funds had been directed to non-veterans expenditures, far higher than other similar groups.

Fletcher said he was hopeful that he would be able to help the fractured organization regain the trust of donors and veterans.

"I look forward to working alongside the WWP executive team to further our mission that makes a meaningful impact in the lives of our warriors, their caregivers and families. WWP has improved the lives of many families, and I will strive to advance these efforts by continuing to prioritize the needs of our injured veterans and their loved ones," said Fletcher.

WWP did not indicate whether it is searching for a temporary CEO.
