An official for the Office of House Employment Counsel (OHEC) testified Thursday sexual harassment claims are among the least popular accusations the congressional office has handled in its two decades of operations.

"We typically see mostly retaliation cases when employees file claims," Gloria Lett, OHEC counsel testified before the Committee on House Administration. "Followed by retaliation is the American with Disabilities Act claims, race claims, Fair Labor Standards Act claims, age, Family and Medical Leave Act, and sex discrimination - gender discrimination cases come in about the same rate."

"It is followed by sexual harassment claims, pregnancy claims. National origin and military discrimination claims come in at about the same rate, and then finally claims based on color," Lett added.

The OHEC official was unable to disclose the number of each type of incident.

The issue recently came up after Rep. Jackie Speier, D-Calif., revealed the Treasury Department had paid out more than $17 million to victims of work-related issues, including harassment, on Capitol Hill.

In the first 10-and-a-half months of this year, the Treasury Department paid $934,754 to Capitol Hill employees who were the victims of various work issues.

Last year, 15 victims were compensated a total of $588,049.

In total, 264 victims have been paid a total of $17 million since 1997.

The Office of Compliance said it chose to release the numbers ahead of their scheduled early 2018 release because of the increasing number of requests in recent weeks.
