The military is investigating the president of the U.S. Naval War College amid allegations that he spent excessively, abused his hiring authority and otherwise behaved inappropriately, including keeping a margarita machine in his office.

Multiple current and former college employees say they have raised serious concerns for over a year about Rear Adm. Jeffrey Harley's conduct at the helm of the elite school, in Newport, Rhode Island, that grooms future admirals and generals.

Dozens of emails and other documents are said to show the college has struggled to make payroll under Harley's leadership and spent about $725,000 annually on raises while facing an annual shortfall of $5 million or more.

Married Harley is also said to have sent a series of campus wide emails to hundreds of students, faculty and staff that raised eyebrows, including offers of 'free hugs' and games of Twister in his office.

In an email sent May 12, Harley boasted about a new portrait of himself, painted on velvet. He attached photos showing the picture hanging in a campus building among those of other college presidents.

'He preferred cats, Star Trek, red wine, baseball and was positively obsessed with achieving the perfect hair day,' according to a label he said he mounted with the picture.

Harley, who is bald, said the portrait was made by a professor who paid for it himself and gave it to Harley as a joke. He called it a way to poke fun of himself.

Harley blamed the fiscal strain on the Navy not fully funding new missions the college has taken on in an interview last month. And he said the emails merely reflected his lighthearted leadership style.

A small group of longtime college employees filed an anonymous complaint in April 2018 with the Navy's office of the inspector general.

The group members said they 'hold no ill-will' toward Harley but that 'his destructive and ethically challenged leadership style is destroying the college,' according to the complaint shared by two of the workers.

They, along with two other current employees and one former worker, spoke about their concerns with Harley on condition of anonymity because they feared professional retaliation.

Two of them said they and others were interviewed by investigators in September, but nothing happened. The group contacted the inspector general again in January with additional allegations of Harley flouting Navy rules and norms.

'The drinking continues. Morale is at an all-time low,' the employees wrote in a January email. 'Your biggest concern should be, however, the financial situation at the college.'

What is the U.S. Naval War College? The elite waterfront college grooms future admirals and generals. It was founded in 1884 when the Navy was still transitioning from wooden ships to steel. The school is in the well-heeled sailing community of Newport in Rhode Island and has served as a pre-retirement post for distinguished wartime commanders. That includes Vice Adm. James Stockdale, the Vietnam prisoner of war and Medal of Honor recipient. Previously an assistant deputy chief of naval operations in Washington, Harley assumed command in July 2016 at the post-graduate institution. Around 1,600 students graduate each year and it employs around 700 faculty and staff. Advertisement

They said they heard nothing again from investigators until last month, after the Associated Press asked the Navy about Harley's conduct.

The Navy confirmed this week that it has received multiple complaints about Harley's behavior. It has not taken action against him so far.

'We do not comment on ongoing investigations,' Navy spokeswoman Lt. Christina Sears said.

Harley said he could not discuss any investigation: 'That's Navy business. But I think you'd be surprised to know that on any given day about 85 officers are under investigation,' he said.

He declined Wednesday to answer a series of questions about additional allegations - including his use of a margarita machine - and sent a campus wide email downplaying the complaints, saying they were from 'a few individuals.'

'All the decisions questioned in the allegations were subject to legal review either before or after the fact, and I believe that all of my decisions are within my authorities,' Harley wrote.

But Harley himself acknowledged in a campus email in February that the school had to make across-the-board cuts to ensure it met payroll. Just last week, he asked for more cutbacks in travel budgets.

All five current and former employees blamed that in part on substantial raises - as much as $10,000 to $15,000 per year - that Harley appeared to grant unilaterally to some faculty, rather than consulting the college's other senior leaders, as is customary.

Harley has told staff and faculty in emails this spring that the college was remedying pay gaps between men and women, balancing pay between departments and creating a system to avoid future disparities.

The employees also complained that Harley had hired unqualified people to high-paying jobs, sometimes exploiting a federal rule meant to allow colleges to quickly hire qualified professors. They questioned Harley's spending of tens of thousands of dollars on certain contractors and others, who they said brought little benefit to the college.

Among the other allegations made with the inspector general's office is that Harley drinks on duty. The employees alleged that Harley has a margarita machine in his office, and that 'he moves the machine to suit his mood,' sometimes to a dining area for school leaders.

'He has invited members of the staff to his office for afternoon drinks, setting his employees up to either comply because he's the boss or uncomfortably decline his offer because they do not want to drink during the workday,' the staffers said in their complaint.

Harley has also sent campus wide emails inviting people to his office for a game of Twister, in which players contort around one another on a mat, or for 'free hugs (if desired)'.

Workers called his often-rambling emails unbecoming of an admiral and said they left people wondering how Harley was spending his time and school resources.

In last month's interview, Harley called himself quirky and said he tries to use humor to break the tension in what can be a high-pressure environment. As a leader, he said, he will hug back appropriately. He said he does not actually own Twister.

'I do not believe there's anything in those emails that are derogatory, unethical, immoral or illegal,' he said.

Harley said he's making decisions in the best interest of the Navy and the college, and he believes his tenure has been extended for a fourth year at the war college, though the Navy is considering hiring a new president who would be a civilian. That would be a first for the college, and it could shorten Harley's time in Newport.
