Two members of the U.S. Senate Select Committee on Ethics sent a letter Friday to the Office of Compliance requesting all of their records on claims of impropriety, a move that follows a series of allegations against current members of Congress.

The letter, signed by committee Chairman Johnny Isakson, R-Ga., and Vice Chairman Christopher A. Coons, D-Del., requested “all records” that are “related to any claims of sexual harassment, discrimination, retaliation, or any other employment practice prohibited by the CAA involving alleged conduct by any current Member, officer, or employee of the Senate.”

According the letter, “sexual harassment or employment discrimination” are not permitted in accordance with federal law and Senate rules.
