WASHINGTON — A nonprofit organization run by one of President Trump’s most prominent African-American allies recently held an event in a black community where it promoted Trump administration policies like criminal justice reform while doling out cash prizes to participants.

The event, a “Christmas Extravaganza” in Cleveland last month, was hosted by a charity group run by Darrell Scott, a longtime Trump surrogate who has also been advising his campaign. Organizers with the group, the Urban Revitalization Coalition, handed out thousands of dollars of cash stuffed in envelopes for an event it advertised as a “$25,000 Cash Giveaway.”

The event was first reported by Cleveland.com.

In an interview, Mr. Scott said that his organization was nonpartisan and that the event had not been organized by the Trump campaign. But he acknowledged that interspersed throughout the event were positive remarks about some Trump administration policies that have affected black communities.

“We talked about the country,” Mr. Scott said. “We said there are a number of things that are benefiting black America right now. For instance, criminal justice reform.” Mr. Trump’s campaign has been highlighting the 2018 passage of the First Step Act, which revised a number of the nation’s sentencing and prison laws, as part of its outreach to African-American voters.
