President Obama’s budget would do a lot of things, but one of the most controversial may to be allowing legal sales of marijuana in the nation’s capital. D.C. voters overwhelmingly approved a ballot measure to legalize pot for recreational use. But in December, outgoing Democrats and incoming Republican leaders in Congress moved to halt the measure. Under a broad budget deal, they prevented the District’s mayor and council from spending any money to work out the specifics of how pot would be sold, which the ballot measure left up to local politicians to decide.
