WASHINGTON — One by one, the women of the Senate stood up, speaking out about the scourge of sexual assault in the military and their collaborative effort to address the long-neglected issue.
First-term Senator Kelly Ayotte, Republican of New Hampshire and a member of the Senate Armed Services Committee, said Tuesday that it was an issue ‘‘that the women of the Senate have really, I think, driven,’’ not necessarily a woman’s issue, but one of justice and fairness.
With several female colleagues listening, four-term Senator Patty Murray, a Washington Democrat, hailed the record 20 women in the 100-member Senate, but insisted that history should not be limited to numbers.
‘‘Instead, it is what we do with our newfound strength to address the issues that are impacting women across the country,’’ said Murray, head of the Senate Budget Committee.
In speech after speech on the Senate floor, Republican and Democratic women — 10 of the 20 — focused on their unity in trying to force Congress to embrace sweeping changes to the decades-old military justice system as part of the annual defense policy bill.
They put aside their bitter differences over how to prosecute the alleged attackers, concentrating on the common ground of how to end the epidemic of sexual assault. The Pentagon estimates that 26,000 members of the military may have been sexually assaulted last year, though thousands were afraid to come forward.
Under the defense bill, commanders would be stripped of their ability to overturn jury convictions, any individual convicted of sexual assault would face dishonorable discharge or dismissal, and a civilian review would be triggered when a decision is made not to prosecute a case. The bill would provide a special counsel for victims and eliminate the statute of limitations for courts-martial.
Senate action on the bill is the culmination of months of work, largely led by the seven women who serve on the 26-member Armed Services Committee — a high-water mark for a panel that for decades was a male bastion.
‘‘This is what the American people wanted, us working together,’’ said five-term Senator Barbara Mikulski, Democrat of Maryland and head of the Senate Appropriations Committee.
Senator Susan Collins, a Maine Republican, said the senators were united by the need for serious changes. Senator Amy Klobuchar, Democrat of Minnesota, spoke of the importance of addressing the crimes. Republican Senator Lisa Murkowski of Alaska, Washington state’s Maria Cantwell, and the newest members, Tammy Baldwin of Wisconsin and Elizabeth Warren of Massachusetts, gave forceful speeches.
In a fractious Congress, the women have persuaded their colleagues to support the changes in a rare instance of bipartisanship. The women represented various stages of Senate experience, but all have displayed some willingness to compromise on certain issues.
On issues that divide them, they are lobbying hard.
Senator Kirsten Gillibrand, Democrat of New York and chairwoman of the Armed Services personnel subcommittee, wants to give victims of rape and sexual assault in the military an independent route outside the chain of command for prosecuting attackers.
Her solution would take the decision from commanders and give it to seasoned military lawyers. The top echelon of the military has opposed her plan and she has faced resistance from a number of Democrats and Republicans.
