Bernie Sanders offers marijuana legalization plan

Sen. Bernie Sanders released a proposal Thursday to legalize marijuana across the country and expunge criminal convictions related to the drug, embracing an overhaul of federal laws on the eve of a presidential forum expected to renew the debate on race, drugs and police violence.

Sanders becomes the latest Democratic White House aspirant to issue a plan for more tolerant drug laws, a shift from past presidential elections when Democrats, like Republicans, often promoted more toughness. Changing attitudes toward drug crimes, and a growing number of states legalizing cannabis, have ushered in a primary where ideas once seen as provocative have become mainstream.
