Russian disinformation operations to exploit racial tensions during the 2016 presidential election in the United States found firm ground in a country where legislators have long sought to suppress the black vote, according to a report released Monday.

The report, “State of Black America,” was released by the National Urban League, a civil rights organization based in New York. It underlined the Russian interference in particular but said that black voting rights were under attack from a wide range of actors, including domestic politicians. 

In about two dozen states, voting restrictions have gotten worse since 2010 because of changes including new voter identification laws and decisions to limit locations where voters can cast ballots, the report said.
