An ethics probe related to the sexual harassment allegations has reportedly been opened.

A report by the Associated Press on Friday indicated that Franks pressured a former staff member to be a surrogate mother for he and his wife, at one point offering the staffer $5 million.

Franks represents Arizona's 8th congressional district, which includes north and west Maricopa County, including the city of Glendale.
