Harish previously told the Daily Mail he didn't think Morrisey's request was necessary because his office is a private practice, receives no public money and follows all state and federal regulations.
"It's almost like asking ... regulating every physician's or dentist's office practice. I guess it's getting a special impetus because it's abortion," Harish said at the time. "I'm sure incidents happen in many medical practices or many dental practices. But it's only because of the abortion that he's putting more focus on it."
Harish expressed a similar concern in his letter.
"We along with doctors and other West Virginians dedicated to women's health are concerned when, if ever, any state official may single out certain health care providers for scrutiny for reasons unrelated to medical care and public health," he said.
Speaking on Tuesday, Harish said he only responded to Morrisey "to be courteous to the attorney general.
"I don't know if I had to or not," he said.
Pro-choice groups like West Virginia Free and the West Virginia chapter of the American Civil Liberties Union questioned Morrisey's motives in sending the letters, suggesting the move was politically motivated.
Morrisey released a letter defending his actions, dismissing the criticisms as "scare tactics."
On Tuesday, his office indicated no disappointment with the clinics' brief responses.
"We will continue our efforts to review the state of abortion regulation in West Virginia and seek to ensure that women's health is protected," he said in a prepared statement.
