Calling the country "very divided and getting worse," Donald Trump said this morning that the country needs a message of unity.

Speaking to Fox & Friends by phone, Trump called for the implementation of "stop-and-frisk" policies in inner cities, specifically citing Chicago. 

"You have to do something. It can't continue the way it's going," he said, calling it "unbelievable" that it isn't used in Chicago, where there have been 3,000 shootings this year.

"It's worse than some of the places we're hearing about like Afghanistan, war-torn nations," he said.

Trump said the controversial policy, implemented in New York City under former Mayor Rudy Giuliani, will allow police officers to identify people with guns and "take the gun away."

Critics say "stop-and-frisk" allows officers to carry out searches that violate a person's constitutional rights.
