The House Committee on Oversight and Government Reform will direct the U.S. Marshals to “hunt down” the former Flint emergency manager who has refused to testify in front of the committee, the top committee lawmaker said Wednesday.

Chairman Jason Chaffetz, R-Utah, said Darnell Earley was invited to testify in front of the committee and on Monday told officials he would not be coming. On Tuesday, Chaffetz’s aides sent a subpoena electronically to Earley’s lawyers, who refused to accept it.
