Fighting for the Overlooked Recognition of Groups Operating in Toxic Test Environments in Nevada (FORGOTTEN) Veterans Act of 2025
This bill requires increased Department of Defense (DOD) documentation related to toxic exposures by military personnel and establishes eligibility for certain disability compensation and benefits for individuals who served at the Nevada Test and Training Range (NTTR).
DOD must (1) expand the Individual Longitudinal Exposure Record to include specified medical information and document all toxic exposures of members of the Armed Forces, and (2) document in service records whether a member of the Armed Forces served at a location with potential toxic exposure.
Members of the Armed Forces and civilian DOD employees who are or have been stationed at specified nuclear facilities must be presumed to have been exposed to toxic substances.
DOD must classify the NTTR as a location where contamination occurred and the Department of the Air Force must identify those who have been stationed there since January 27, 1951.
The bill establishes that onsite participation on or after January 27, 1951, at NTTR locations where there was a potential of toxic exposure is a radiation-risk activity, therefore providing a presumption of service-connection for specified conditions.
The bill also establishes a presumption of toxic exposure for veterans who performed active service at NTTR locations with potential toxic exposure, including airspace above such locations. Additionally, lipomas and tumor related conditions must be considered as service-connected conditions for veterans who served at the NTTR locations.

This bill requires individuals to provide documentary proof of U.S. citizenship when registering to vote, and requires photo identification to vote, in federal elections.
Specifically, the bill prohibits states from accepting and processing an application to register to vote in a federal election unless the applicant presents documentary proof of U.S. citizenship.

Further, the bill (1) prohibits states from registering an individual to vote in a federal election unless, at the time the individual applies to register to vote, the individual provides documentary proof of U.S. citizenship; and (2) requires states to establish an alternative process to demonstrate U.S. citizenship.
Each state must take affirmative steps on an ongoing basis to ensure that only U.S. citizens are registered to vote, which shall include establishing a program to identify individuals who are not U.S. citizens using information supplied by certain sources.
Additionally, states must remove noncitizens from their official lists of eligible voters.
The bill (1) provides for a private right of action for certain violations, and (2) establishes criminal penalties for certain offenses.
Individuals voting in federal elections must present an eligible photo identification document. An individual who votes by absentee ballot must submit a copy of their identification document with both the request for, and the submission of, the absentee ballot.
