WASHINGTON (AP) — The House Ethics Committee announced Thursday it is investigating Republican Rep. Chuck Edwards of North Carolina over allegations that he created a hostile work environment and engaged in sexual harassment.

Edwards, serving his second term in the House, said he welcomed the inquiry and planned to fully cooperate with the committee.

“I am confident the investigation will expose the facts, not politically motivated fiction,” Edwards said.

The investigation follows an Axios report stating that three sources told the publication that they witnessed conduct by Edwards toward two female staffers in their 20s that they described as inappropriate. The sources said Edwards’ behavior crossed professional boundaries and created an uncomfortable work environment. Axios said the sources were granted anonymity to protect against retaliation.

The Ethics Committee said in its investigation announcement that it would make no further public comment on the matter and that disclosing the review does not, by itself, indicate that any violation occurred.

The committee’s investigation comes at a time of heightened scrutiny of lawmakers’ behavior toward female staffers following the resignations of Democratic Rep. Eric Swalwell and Republican Rep. Tony Gonzales. Both were facing calls for their expulsion before they stepped down.
