The Office of Congressional Ethics referred five matters to the House ethics committee for formal review, according to a report issued Monday.

The OCE, which is tasked with reviewing potential rules violations and recommending investigations to the full Committee on Standards of Official Conduct, began work in January. The recommendations made May 29, included in a quarterly report issued by the OCE, mark the first time the fledgling office has advocated for formal investigations by the ethics panel.

The office also issued one report to the ethics committee advising a matter be dismissed.

The ethics committee has 45 days after receiving a recommendation from the OCE to review the matter and publish the report to the public. The committee can vote to extend that period an additional 45 days.

Details of the investigations are not included in the OCE report.
