WASHINGTON (AP) — Donald Trump says there’s a “lack of spirit” between blacks and whites after two high-profile police shootings of black men and violent protests in Charlotte, North Carolina.

In a phone interview Thursday on “Fox & Friends,” Trump said “there has to be a unity message somehow that has to get out and it starts with leadership.”

The Republican presidential candidate’s comments comes as he increasingly reaches out to African-American voters, at the same time as maintaining the tough law-and-order stance that appeals to core supporters.

He repeated his support for “stop-and-frisk,”a tactic which allows police to stop and search anyone they deem suspicious. A federal judge has ruled it discriminatory.

Trump said “it’s quite unbelievable” that it’s not being used in Chicago.

He said: “Chicago is out of control.”
