JACKSON, Miss. — President Donald Trump’s campaign is telling a Mississippi group to stop saying that Trump supports a ballot measure that would legalize medical marijuana in the state.

Mississippians for Compassionate Care is a group promoting Initiative 65. It paid for a letter signed by several prominent Republicans, and the outside of the envelope said: “Join President Trump and 3 out of 4 Mississippi Republicans who support medical marijuana.”

The letter said: “President Trump Supports Medical Marijuana ... and allowing states to decide on that issue.”
