The Republican running for governor in New Jersey is going to Washington to testify about white-collar crime settlements he approved as U.S. attorney. Chris Christie is to appear Thursday before a congressional subcommittee investigating deferred prosecution agreements. The arrangements allow companies accused of crimes to avoid trials by agreeing to federal oversight. The deals are overseen by hand-picked monitors who are paid millions. As New Jersey’s top U.S. prosecutor, Christie approved several deals. One was worth $52 million and was given to his former boss, former attorney general John Ashcroft. Democratic Rep. Frank Pallone of New Jersey says Christie appointed GOP donors and friends. Christie has denied any conflicts. AP.
