TRENTON - New Jersey's Republican candidate for governor has been asked to testify before a congressional subcommittee on white-collar-crime settlements he brokered as U.S. attorney.

Campaign manager Bill Stepien confirmed receipt of a letter Tuesday inviting Chris Christie to testify at the June 25 hearing on deferred-prosecution agreements. DPAs are lucrative, no-bid contracts given to lawyers to oversee deals between the U.S. Attorney's Office and companies accused of wrongdoing.

Several contracts awarded under Christie have raised concerns, including his hiring of former Justice Department boss John Ashcroft, whose firm made up to $52 million in one deal. *
