USA Mary Beth Buchanan cited in the DOJ politicization report.

TPM:

The report concludes, however, that Goodling never substantiated the allegations of financial improprieties and that Hagen's rumored sexual orientation was the reason she was not allowed to remain at Main Justice. One of the witnesses cited in the report is Mary Beth Buchanan, the former executive director of the EOUSA who remains the U.S. Attorney in Pittsburgh:

Buchanan said that Goodling told her that the AUSA and the U.S. Attorney were involved in a relationship, and that it would not be appropriate for the Department to do anything to further that relationship, such as employing them in the same geographic area. According to Buchanan, at that time the U.S. Attorney was trying to find a position in the Washington, D.C. area. Buchanan said she understood that Goodling was telling her not to select the AUSA because it would look like the Department was sanctioning the homosexual relationship.

As to the veracity of the rumors that surrounded Hagen and Chiara, Hagen's attorney described them as "completely false" in the interview with TPMmuckraker. "There was nothing to verify that my client was gay -- she never identified as such," Banks said. "The supposed relationship between her and the U.S. attorney was completely false, and nothing more than co-workers and friends. There was no improper relationship. No improper government trips. No improper bonuses."
