The commander of the Wisconsin National Guard agreed to resign at Gov. Tony Evers' request Monday, following the release of a scathing federal report that found the Guard defied federal law, regulations and policies for years over the handling of soldiers' sexual assault and harassment complaints.

The report from the National Guard Bureau in Washington, D.C., found the Guard allowed internal investigations in defiance of federal law as well as Department of Defense and bureau policy; investigators falsely presented themselves as working for the federal bureau; case records were mismanaged; and Guard sexual assault response policies were not in compliance with federal regulations for more than five years.

Evers' office said in a statement that the governor asked the Guard's top leader, Maj. Gen. Donald Dunbar, to resign hours before his administration released the report Monday afternoon. Dunbar agreed to step down on Dec. 31.

Evers appointed Brig. Gen. Gary Ebben — the assistant adjutant general of the Wisconsin Air National Guard — as interim commander and will choose a permanent replacement, his office said. The governor also ordered the Guard to implement all of the report's recommendations by September.

"I am extremely upset and concerned with the ... findings," Evers said in a statement. "Our service members deserve to be safe and supported while carrying out their important mission."

Wisconsin National Guard spokesman Joe Trovato referred a request for comment to Evers' office.

Dunbar is the nation's longest-serving state National Guard commander. He was appointed in 2007 by then-Gov. Jim Doyle, a Democrat. He has earned numerous commendations, including the Legion of Merit award for exceptional command performance. But the Guard has been shaken by recent allegations of officers brushing off sexual assault complaints and retaliating against victims for reporting incidents.

Evers and U.S. Sen. Tammy Baldwin asked the National Guard Bureau in March to review the Wisconsin National Guard's sexual assault reporting and investigative protocols. The bureau spent nearly seven months on the review, meeting with more than 1,600 Guard leaders and members.

Among the key findings:

—The Wisconsin Guard ignored Defense Department polices and procedures by personally directing the Guard to conduct internal administrative investigations in 22 of 35 cases reported between 2009 and 2019. Department regulations call for cases to be referred to local police for criminal investigation and the National Guard Bureau for administrative investigation.

—Internal investigators were poorly trained and their probes lacked oversight, often resulting in incomplete findings and recommendations. They sometimes falsely presented themselves as bureau investigators.

—Victims were told to waive their right to criminal investigations by local police.

—Complaints weren't properly tracked and data was never entered in a Defense Department database as required.

—The Guard was supposed to have 28 victim support advocates to help sexual assault and harassment victims but had only one.

—The Guard's sexual assault policies haven't been updated since 2013 and don't include changes to federal laws and regulations.

—Guard officials reached an agreement with the state Justice Department in October 2018 spelling out that the Guard could refer sexual assault cases to the department. The report referenced an email written by then-Attorney General Brad Schimel's chief of staff saying the agreement was meant to "get the federal National Guard Bureau off the back" of Dunbar.

—Either the victim or the accused perpetrator or sometimes both carried loaded weapons while the investigation was ongoing, leaving open the possibility that one of them could shoot the other in retaliation.

—Guard officials didn't note substantiated sexual offenses in offenders permanent evaluation records.

—Every state's National Guard was ordered to implement a reprisal prevention plan in 2017 to encourage personnel to file complaints without fearing retaliation but Wisconsin officials never implemented one.

Evers on Monday ordered the Guard to implement changes detailed in a corrective action plan submitted by bureau investigators, including updating written policies and communicating all disciplinary actions down to the company level. The bureau will oversee the implementation and conduct another review to ensure every issue has been addressed. The order also calls for the creation of an outside ombudsman who will oversee sexual assault complaints within the Guard.

Baldwin said in a statement that Guard members deserve a work environment free of sexual assault, harassment and fear of retaliation.

"The failure of leadership, wrongdoing, and lack of accountability that has been uncovered demands change at the Wisconsin National Guard, including new leadership and implementing all of the report's recommendations," Baldwin said.

Allegations that Wisconsin Guard officers had been brushing aside sexual assault complaints and retaliating against victims came to light in November 2018 when Master Sgt. Jay Ellis complained to Baldwin about half a dozen incidents within his 115th Fighter Wing security squadron. Ellis wrote in a letter to the senator that his unit considers sexual misconduct "no big deal."

One of the women involved in an incident Ellis cited told The Associated Press that officers sexually assaulted her and a friend during a 2002 party at a training base. She didn't file a formal complaint because she feared reprisal. She did report the assault to her fire team commander, who passed on the report to a senior master sergeant, but the efforts resulted only in the woman being harassed.

Ellis' letter spurred a U.S. Air Force investigation that's still underway.

State Senate Majority Leader Scott Fitzgerald, a Republican who is running for Congress in 2020, asked Dunbar in February for a complete review of Guard protocols for handling sexual assault complaints. Fitzgerald made the request after meeting with a female soldier who told him she twice informed brigade leaders in 2014 that a master sergeant had been sexually harassing and inappropriately touching her and her colleagues. She said an investigator and rank reduction board found the master sergeant had acted inappropriately but he was allowed to retire with no punishment and was later hired back as a contractor.

Dunbar refused to launch such a probe, instead outlining the protocols in a letter to Fitzgerald and stressing that the Guard has "zero tolerance" for sexual misconduct.

Evers and Baldwin then stepped in and asked the bureau for the review.
