Arizona Republican Congressman Trent Franks will step down from his post amid an investigation into allegations of sexual harassment. In a statement, Franks remarked that he and his wife have had infertility problems, and that he discussed surrogacy with two previous female staffers. Franks said he regrets the discussion caused distress in the workplace. Franks added that he's convinced his story would become distorted and sensationalized before a fair House Ethics investigation could take place. He said he has notified House leadership that he'll be leaving Congress as of January 31st.The Republican released his statement shortly after the House Ethics Committee announced that it's organizing a subcommittee to investigate allegations of sexual harassment against Franks. Franks insists he never physically coerced or attempted to have sexual contact with any member of his staff.
