Servicemembers and Veterans Empowerment and Support Act of 2025
This bill modifies and implements policies and procedures related to Department of Veterans Affairs (VA) health care and benefits for veterans who have experienced military sexual trauma (MST), which is generally defined as physical assault of a sexual nature, battery of a sexual nature, or sexual harassment that occurred while the veteran was serving in the military.
In the case of any veteran who claims that a covered mental health condition (e.g., post-traumatic stress disorder) based on MST was incurred or aggravated by active service, the VA must consider (1) a diagnosis of the condition by a mental health professional, (2) a medically proven link between current symptoms and MST, and (3) credible corroborating evidence that MST occurred.
The VA may not deny a veteran's claim of compensation for a covered mental health condition based on MST without first (1) advising the veteran that nonmilitary evidence and behavioral evidence may constitute credible corroborating evidence, and (2) allowing the veteran an opportunity to furnish the corroborating evidence or advise the VA of potential sources of such evidence.
The Veterans Benefits Administration must conduct an annual special focus review on the accuracy of the processing of claims for disability compensation for disabilities relating to MST.
Additionally, the bill (1) expands eligibility for MST counseling and treatment to former members of the reserve components regardless of duty status, and (2) requires various outreach by the VA to inform potentially eligible individuals about MST care.

Privacy Act Modernization Act of 2025
This bill strengthens privacy protections that apply to personal data held or maintained by government agencies. These protections restrict the storage, access, use, and disclosure of personal data, such as an individual’s name or Social Security number.
Currently, these protections apply to U.S. citizens and permanent residents. The bill expands this to include natural persons in the United States and certain associations and corporations.
The bill places additional limits on the use and disclosure of such data, including by limiting the use of records to a legally authorized purpose and requiring disclosures to be minimal and consistent with a previously stated use.
The bill also increases existing penalties and creates additional criminal penalties for violations. For example, under the bill, an agency employee who willfully discloses individually identifiable information with the intent to sell, transfer, use, or disclose such information for commercial advantage, personal gain, or malicious harm shall be guilty of a felony and fined not more than $250,000, imprisoned for not more than 10 years, or both.
Courts may provide preliminary relief and, if the U.S. is found to have acted intentionally or willfully, the U.S. is liable for additional types of damages (e.g., punitive).
The bill generally takes effect two years after the date of enactment. However, the bill takes effect immediately upon enactment with respect to certain actions taken by the Department of Government Efficiency (DOGE), certain special or temporary employees, and other related individuals and organizations.
