Democratic senators are putting pressure on the Biden administration to use its authority to deschedule cannabis, as a Senate proposal to legalize marijuana faces an uphill battle. Democrats press Biden to use ‘existing authority’ to take step toward marijuana legalization Sens. Elizabeth Warren (D-Mass.), Bernie Sanders (I-Vt.), Cory Booker (D-N.J.) and others on Wednesday sent a letter calling on the Biden administration to “use its existing authority to (i) deschedule cannabis and (ii) issue pardons to all individuals convicted of nonviolent cannabis-related offenses.”
