Maryland Gov. Wes Moore announced Friday he will veto a measure to create a commission to study potential slavery reparations in the state, saying that while it was a difficult decision, the issue already has been studied and now is the time “to focus on the work itself.

Wes Moore, the nation’s lone sitting Black governor, diverged from fellow Democratic governors in rejecting a measure that would have studied reparations.

Maryland Gov. Wes Moore on Friday vetoed a bill that would have required the state to define the economic harms to Black descendants of enslaved people and recommend remedies, dealing a blow to reparations supporters who counted on the only Black governor of a U.S. state to be an ally.
