Senators Chuck Grassley (R - Iowa) and Dick Durbin (D - Illinois) have introduced the Prohibiting Punishment for Acquitted Conduct Act of 2019, which would bar federal judges from considering conduct/acts that underlay charged crimes for which a defendant was found not guilty or which was dismissed by motion. There is a press release from Senator Grassley's office. The United States Sentencing Guidelines now permit conduct for which a defendant has been acquitted to be considered to increase a defendant's sentence, so a criminal sentence can be longer based on some alleged crime that was not proven.
Prof. Doug Berman has a good post on his blog, Sentencing Law and Policy, "Senators Durbin and Grassley Introduce 'Prohibiting Punishment of Acquitted Conduct Act of 2019.'"
