Continuing Appropriations Act, 2020, and Health Extenders Act of 2019 This bill provides FY2020 continuing appropriations to federal agencies through November 21, 2019. It is known as a continuing resolution (CR) and prevents a government shutdown that would otherwise occur when FY2020 begins on October 1, 2019, if the 12 regular appropriations bills that fund the federal government for FY2020 have not been enacted. The CR funds most projects and activities at the FY2019 levels with several exceptions that provide funding flexibility and additional appropriations to various programs. Additionally, the CR extends several programs that are scheduled to expire at the end of FY2019, including several health programs, the National Flood Insurance Program, the Temporary Assistance for Needy Families (TANF) program and related programs, several authorities related to immigration, the Calfed Bay-Delta Authorization Act, the Department of Education's National Advisory Committee on Institutional Quality and Integrity, the Export-Import Bank of the United States, and the U.S. Commission on International Religious Freedom. The bill also includes a provision that permits the Department of Agriculture to continue making payments to farmers affected by retaliatory tariffs by accelerating reimbursements to the Commodity Credit Corporation for certain net realized losses sustained in FY2019.
