The Environmental Protection Agency (EPA) has filed an appeal with the U.S. Court of Appeals for the 9th Circuit requesting continued registration of glyphosate while the Agency reviews scientific data.  The filing is opposed by environmental activist groups and farmworker unions that are demanding de-registration of glyphosate-containing herbicides.  The EPA re-registered glyphosate in January 2020 with appropriate changes to labels.  Activist groups who are party to the litigation claim that the EPA neglected to assess risks to human health and endangered species.
