This bill establishes a one-time grant program to support the National September 11 Memorial & Museum at the World Trade Center. The Secretary of Homeland Security is authorized to award an eligible 501(c)(3) organization operating the museum a grant ranging from $5,000,000 to $10,000,000 , specifically for its operation, security, and maintenance. The Secretary will determine the exact grant amount based on criteria such as the museum's security needs, visitor numbers, preservation efforts, and commitment to educating future generations and increasing access for economically disadvantaged visitors. To receive this funding, the eligible entity must agree to several conditions. These include providing free admission to active and retired members of the Armed Forces, 9/11 first responders, and family members of victims, as well as offering dedicated free admission hours for the general public at least once a week. Additionally, the museum must allow for annual Federal audits of its financial statements, including revenues from ticket sales, donations, and grants, with these audits subject to public review. The recipient is also required to submit annual reports to Congress detailing how the grant funds were obligated or expended.
