House Democrats are asking Metro’s inspector general to review the conduct of two former members of the Metro board, Jack Evans and Corbett Price, both of whom resigned from their posts on the board amid fallout related to an ethics investigation into Evans behavior.

In a letter sent Thursday to Geoffrey Cherrington, Representatives Elijah Cummings and Gerald Connolly (Democrats from Maryland and Virginia, respectively) ask for a probe into accusations of ethics violations from Evans, as well as allegations that both Evans and Price threatened and harassed other Metro employees in an attempt to keep the results of an ethics investigation secret.

Cherrington told the Washington Post on Friday that he plans to follow through on the request. “Of course we’ll investigate it,” he said, “but we’re evaluating what our next steps are going to be.”

Evans, who is also the Ward 2 Councilmember, is in the midst of a wide-reaching ethics scandal related to potential conflicts of interest in his work both on the D.C. Council and on the Metro board. The Metro board’s ethics committee began an investigation into Evans’ conduct in March of this year, following a number of reports about potential ethics violations. That investigation wrapped up in May, but its findings were not released to the public for more than a month, and Evans at first claimed that the committee had cleared him of all violations.

This turned out not to be true, and Evans was eventually forced to admit it. The committee had found him guilty of one ethics violation related to a $50,000 consulting contract with a company called Colonial Parking. In June, the Washington Post obtained a 20-page memo by the outside law firm the Metro board ethics committee retained to complete its investigation into Evans, and it outlined a dizzying list of violations. The release of that memo prompted Evans to step down from the board.

And that’s not even the end of the story. After the Metro board’s ethics investigation concluded—while Evans was denying he’d been found guilty of anything—he and Price were reportedly berating and threatening Metro employees to keep them from disclosing the results, per a Post investigation. While much of the initial heat fell on Evans, Price eventually came under fire, too, for backing Evans up in telling the public he had been cleared of all ethics violations and for reportedly joining him in a campaign of berating phone calls against Metro staffers.

Price resigned at the end of August, citing a medical procedure and a “personal family matter.”

In July, the House Committee on Oversight and Reform and the Subcommittee on Government Operations inserted itself into the scandal, asking the Metro board for more information about its investigation into Evans. WMATA provided 900 pages of documents, per the letter sent on Thursday. Earlier this week, House Republicans asked Democrats to obtain more information in the probe, including transcribed interviews with various parties. That letter, obtained by DCist, also mentions possible obstruction by Evans and Price, and argues that it has a . “This investigation has a direct bearing on matters currently before the Committee, including the announced hearings on statehood for the District of Columbia and [Metro] oversight.”

The letter to the inspector general does not mention statehood, but expresses grave concern at Evans’ and Price’s alleged conduct.

Several people involved in the brouhaha are set to testify before the Subcommittee on Government Operations, which oversees Metro, on October 22, per the Post. The Metro Inspector General is one of them.
