Democratic presidential candidate Sen. Kamala Harris (D-Calif.) on Monday unveiled an expansive vision of criminal justice reform.

The ambitious plan from Harris a former prosecutor and California attorney general who has faced criticism from the left for her record on criminal justice would rejuvenate federal oversight of local police departments, end federal mandatory minimums, legalize marijuana on the federal level, establish a national deadly force standard, and increase federal funding to support police officers mental and physical health.

The proposal includes many elements that would require congressional authorization, some of which would be a tough lift unless Democrats took control of the Senate.

Americans deserve a criminal justice system that focuses on fairness, rehabilitation, and accountability to build trust and safe communities, Harris said in a statement. We can end mass incarceration and combat the bias and racism that fuels it. We can ensure accountability for all parts of the system to build foundations of trust in our communities. We can stop profit from incarceration and stop criminalizing poverty. As president Ill fix this broken system to make it fairer and more accountable for communities across the country.
