Washington (CNN) In an open letter to Senate and House leaders on Thursday, seven ex-congressional aides urged lawmakers to complete long-stalled sexual harassment legislation on Capitol Hill.

The congressional aides, who are all women, said in their letter which was posted on the ACLU website that they are "dismayed and disheartened by Congress' failure to act and take care of its own" after months of delayed negotiations have yet to finalize workplace harassment policies in Congress.

"We hoped that our experiences -- and those of many more who remain nameless -- would spur Congress to fundamentally reform the deeply flawed system it now uses to address claims of harassment and discrimination," the letter states.

In the year since the #MeToo movement inspired several public claims of sexual assault against members of Congress, little progress has been made to reform the Hill's policy against harassment and misconduct. The House passed a sexual assault reform bill seven months ago, three months before a similar bill passed in the Senate, but a complete reform to current legislation has yet to occur.

"These true stories of harassment, abuse, and discrimination are a stain on the institution we love and have profoundly changed the lives of those who experienced them," the women wrote in the letter. "After each of us came forward, we were met with countless, heartbreaking stories from current staffers with similar experiences, and we know that many, many more stories still remain untold."
