The St. Louis circuit attorney's office says it hired private investigators from Michigan to ensure an independent investigation into Missouri Gov. Eric Greitens.
Greitens' attorney Edward Dowd Jr. questioned the arrangement Tuesday while suggesting that local police should have been used.
But Susan Ryan, a spokeswoman for Circuit Attorney Kim Gardner, said local police directed them to the FBI, which said it didn't have jurisdiction to help.
An agreement filed in court Tuesday shows Enterra LLC of Rochester Hills, Michigan, was to be paid a retainer of $10,000 for the investigation.
A grand jury indicted Greitens last week on an invasion of privacy charge stemming from a compromising, nonconsensual photo he allegedly took of a woman with whom he had an affair in 2015.
