Democracy Is Strengthened by Casting Light On Spending in Elections Act of 2026 or the DISCLOSE Act of 2026
This bill addresses campaign finance, including by expanding the prohibition on campaign spending by foreign nationals, requiring additional disclosures of campaign expenditures, and requiring additional disclosures regarding certain political advertisements.
Specifically, the bill expands existing foreign money prohibitions to include disbursements for paid web-based or digital communications and federal judicial nomination communications. It also prohibits foreign nationals from contributing to campaigns related to ballot initiatives and referenda.
The Government Accountability Office must, for each four-year election cycle, study and report on the incidence of illicit foreign money in federal elections.
Next, the bill makes it unlawful to establish or use a corporation, company, or other entity with the intent to conceal an election contribution or donation by a foreign national. A violator is subject to criminal penalties—a fine, a prison term of up to five years, or both.
Covered organizations (e.g., corporations, labor organizations, and political organizations) must, within 24 hours, file reports with the Federal Election Commission to disclose campaign expenditures of more than $10,000 during an election cycle.
The bill also requires organizations to provide additional disclosures regarding political advertisements, including the donors who contributed the most money to that organization in the last year.

Additionally, the bill allows Supporting Effective Instruction State Grants to be used to assist local educational agencies (LEAs) and schools in recruiting, hiring, and retaining state-certified school librarians.
Further, the bill authorizes states and LEAs to use Student Support and Academic Enrichment grants for programs and activities that promote the development of digital literacy and information literacy skills.
The Department of Education (ED) must direct the National Center for Education Statistics to biennially collect data on school libraries.
ED must require an assurance from each state and LEA receiving certain funds confirming that it will (1) protect the First Amendment rights of students in school libraries, and (2) provide equal protection in the conduct of school libraries in compliance with the requirements of the Fourteenth Amendment and nondiscrimination laws.
The bill also provides liability protection to teachers, school librarians, school leaders, paraprofessionals, and other staff for actions that conform with state or local policies regarding the right to read.
