Donald Trump, Republican presidential candidate has appeal to African-American voters directly, saying “What do you have to lose?”
Mr Trump told almost all white audience in Michigan that black voters “are living in poverty” and their “schools are no good”.
He promised to “provide” for African-Americans where Democrats had failed.
“If you keep voting for the same people, you will keep getting exactly the same result,” he said.
He said Democrat Hillary Clinton, his opponent, “would rather provide a job to a refugee” than to unemployed black youths, “who have become refugees in their own country”.
The Friday speech was the third time this week that Mr Trump sought to appeal to African-American voters.
On several occasions, African-American protesters have been assaulted by Trump supporters at rallies. A New York Times investigation found supporters frequently use racist language at rallies.
Some analysts say Mr Trump, trailing badly in national polls for weeks, desperately needs to broaden his appeal beyond his base of white working-class voters.
