Chicago Mayor Rahm Emanuel has clarified his earlier remarks, saying the city would welcome U.S. Justice Department involvement in helping restore trust in the Chicago police.

Emanuel sent out a statement Thursday, a day after saying that a federal civil rights investigation into the police department's tactics would be "misguided" because the U.S. Attorney's office in Chicago already is investigating.

Democratic presidential candidate Hillary Clinton and Illinois Attorney General Lisa Madigan are among those calling for an investigation by the U.S. Department of Justice's Civil Rights Division to determine whether the police department's practices violate federal and constitutional law.

Emanuel says he trusts federal officials "to make the right decision" and is "open to anything" that would restore trust in the city's public safety efforts.
