Today, Mr. Nance is involved in a messy, distracting power struggle. Often, that plays out on Twitter, where Mr. Nance taunted one former ally as “fat” and an associate of “a verified con artist.”
He accused a pro-Ukraine fund-raising group of fraud, providing no evidence. After arguing with two Legion administrators, Mr. Nance wrote a “counterintelligence” report trying to get them fired. Central to that report is an accusation that one Legion official, Emese Abigail Fayk, fraudulently tried to buy a house on an Australian reality TV show with money she didn’t have. He labeled her “a potential Russian spy,” offering no evidence. Ms. Fayk denied the accusations and remains with the Legion.

Mr. Nance said that as a member of the Legion with an intelligence background, when he developed concerns, he “felt an obligation to report this to Ukrainian counterintelligence.”
The dispute goes to the heart of who can be trusted to speak for and raise money for the Legion.
Mr. Nance has left Ukraine but continues fund-raising with a new group of allies. One of them, Ben Lackey, is a former Legion member. He told his fellow volunteers that he was once a Marine and wrote on LinkedIn that he had most recently been an assistant manager at LongHorn Steakhouse. In fact, the Pentagon said he had no military experience (and he worked as a server, the steakhouse said).
In an interview, Mr. Lackey said that he lied about being a U.S. Marine so he could join the Legion.
