WASHINGTON — Protection Secretary Lloyd J. Austin III instructed to lawmakers on Thursday that he supported alterations to the way the army handles sexual assault situations, but he declined to endorse a evaluate lengthy pushed by Senator Kirsten Gillibrand, Democrat of New York, that would slice the navy chain of command out of the prosecution of lots of other really serious crimes as well.

Mr. Austin’s support for changes all over sexual assault circumstances signifies a big change for army management, which has very long resisted calls to end the practice of dealing with this kind of scenarios by means of the chain of command. But his opposition to broader modifications to the army justice program proposed by Ms. Gillibrand could set up a showdown among a bipartisan team of senators and the Pentagon.

“Clearly, what we have been carrying out hasn’t been operating,” Mr. Austin reported in remarks before the Senate Armed Services Committee. “One assault is far too several. The quantities of sexual assaults are even now far too large, and the self esteem in our system is continue to much too low.”

Fairly than embrace Ms. Gillibrand’s bill, Mr. Austin appeared to endorse the recommendations of a panel he appointed to examine the situation before this calendar year. That panel suggested that unbiased army lawyers consider over the role that commanders presently perform in selecting whether or not to court-martial those accused of sexual assault, sexual harassment or domestic violence.

“The issues of sexual assault and sexual harassment,” Mr. Austin claimed, “are the issues we are attempting to take care of and strengthen.”

President Biden has signaled his aid for Ms. Gillibrand’s broader technique, at least for now. Her bill has obtained guidance from at the very least 70 users of the Senate — which include many who voted from the similar invoice in 2014, arguing it would undermine commanders — and key users in the Household.

Senator Jack Reed, Democrat of Rhode Island and chairman of the Armed Expert services Committee, thinks Ms. Gillibrand’s bill goes much too much, and he has been doing work powering the scenes with Pentagon officers to rein it in.

“I want to be sure that regardless of what variations to the U.C.M.J. that I recommend to the president and in the end to this committee, that they are scoped to the difficulty we are striving to address, have a obvious way forward on implementation, and finally restore the self-assurance of the drive in the method,” Mr. Austin stated, referring to the Uniform Code of Army Justice, which is the basis of the American armed service authorized process. “You have my motivation to that, and also my dedication to working expeditiously as you take into consideration legislative proposals.”

Mr. Austin’s remarks could set off an rigorous political struggle about which method Congress will get. It will check the electricity of Ms. Gillibrand among her bipartisan Senate allies, which includes Senator Chuck Schumer, Democrat of New York and the the vast majority leader, who could be pressured to select sides in deciding the measure’s destiny.

In either function, it seems distinct that commanders are all but specific to get rid of total control over sexual assault prosecutions. “Change is coming to the office,” Mr. Reed reported.

Ms. Gillibrand and a single of her Republican colleagues on the committee, Senator Joni Ernst of Iowa, even more pressed Mr. Austin on his sights of the difficulty throughout the hearing. Ms. Gillibrand suggested that failure to include other severe crimes in the legislation would lead to racial disparities in courtroom-martial scenarios, which seemed to be portion of a method to enchantment to the remaining skeptical customers of Congress and Mr. Austin.

But whilst Mr. Austin took pains to praise Ms. Gillibrand’s perform on the matter about the previous ten years, he also signaled that he did not help the wide nature of her legislation.

“Whatever improvements arise going ahead will be mostly thanks to your remarkable dedication to this issue,” he advised Ms. Gillibrand. “As you know, Senator, I always have an open intellect to resolving any hard difficulty,” he mentioned, incorporating that his commission experienced been centered on sexual assault and harassment.

When he was confirmed by the Senate, Mr. Austin claimed that dealing additional forcefully with sexual assault would be a top rated priority. In February, he appointed the unbiased fee to analyze the difficulty and give recommendations that he and the support chiefs could take into consideration.

The customers of the panel are trying to find to make a new profession keep track of in the Defense Department in which choose advocates standard — armed service legal professionals — would be specially properly trained to offer with this sort of situations. This on your own would be a main shift in how the army does points. Mr. Austin has reported he desires the service chiefs to overview the tips.

Kathleen Hicks, the deputy defense secretary and the very first female to serve in the No. 2 purpose at the Pentagon, and General Mark A. Milley, chairman of the Joint Chiefs of Staff, have both equally said they have grow to be confident that the latest system does not serve victims perfectly.

“I have some proof, some scientific studies, some anecdotal proof that junior customers of the military services, principally gals, have shed religion and confidence in our chain of command to resolve sexual assault by way of the chain of command,” Common Milley explained Thursday.

But bringing in other felonies to any overhaul of the army justice system, he mentioned, “requires some detailed study,” introducing that he had “a finish open up brain on this.”

A report out of Fort Hood, Texas, final 12 months that in-depth a tradition of harassment and abuse gave fuel to Ms. Gillibrand’s evaluate and parallel endeavours in the Dwelling.

In 2019, the Protection Office observed that there were being 7,825 reports of sexual assault involving support members as victims, a 3 % boost from 2018. The conviction amount for scenarios was unchanged from 2018 to 2019 7 % of situations that the command took action on resulted in conviction, the lowest rate due to the fact the section commenced reporting sexual assault cases in 2010.

Leaving the listening to, Ms. Gillibrand appeared undeterred in her thrust for her own legislation.

“This is a thing that the majority of the committee has presently fashioned a look at on,” she explained to reporters. “There are so couple of items of laws in Congress currently that both equally Liz Warren and Ted Cruz assistance, a person that both of those Chuck Schumer and Mitch McConnell aid. This is widely bipartisan, has the majority of the committee, and this is not a new challenge.”
