"This country should in no way tolerate the hatred that the KKK, neo-Nazis, fascists and other hate groups spew", Marshall sued Bell and the city for violating the Alabama Memorial Preservation Act, which prohibits the "relocation, removal, alteration, or other disturbance of any monument on public property that has been in place for 40 years or more". In July 2017, Texas attorney general Ken Paxton led a group of Republican attorneys general from nine other states, including Steve Marshall, plus Idaho governor Butch Otter, in threatening the Donald Trump administration that they would litigate if the president did not terminate the Deferred Action for Childhood Arrivals (DACA) policy that had been put into place by President Barack Obama. Tennessee attorney general Herbert Slatery subsequently reversed his position. In 2018, Marshall's opponent, Troy King, accused him of violating campaign finance laws by accepting money from a banned political action committee. In 2019, attorneys general from all 50 U.S. states, the District of Columbia, and all four U.S. territories were urged by the National Association of Attorneys General to support a bill, the Secure and Fair Enforcement (SAFE) Banking Act (H.R. 1595), sponsored by U.S. representative Ed Perlmutter (D-Colo.), which would permit marijuana-related businesses in states and territories to use the banking system. The bill would facilitate collection of taxes levied on the $8.3 billion industry, reduce the danger of operating cash-only businesses and more effectively monitor the industry. Only Marshall and 16 other attorneys general did not support the measure. In June 2020, Marshall threatened to prosecute the city of Mobile and levy a $25,000 fine for removing the confederate memorial Statue of Raphael Semmes during George Floyd protests, if the removal became permanent. Marshall is co-chair of Alabama governor Kay Ivey's Opioid Overdose and Addiction Council. In October 2020, Marshall successfully led a challenge to the Supreme Court of the United States which struck down a federal court-order allowing curb-side voting in Alabama as an accommodation for voters worried about contracting COVID-19. Marshall declined to throw out the conviction of death row inmate Toforest Johnson despite a dearth of evidence of his guilt and widespread support by legal scholars to throw out the conviction. A Jefferson County conviction integrity unit flagged Johnson's case, leading the county's district attorney to recommend that Johnson be given a new trial.
