Questions have been raised about the timing of Therriault's hiring and the legality.
Therriault resigned as a lawmaker last year to join Parnell's administration in the new post. Lawmakers aren't allowed to take positions created while they were in office for at least a year.
Parnell has defended the hire, saying he acted in good faith and relied on Department of Law advice. He said he wasn't governor when Therriault was "in session, as a legislator" and was standing on legal precedent and practice.
His spokeswoman, Sharon Leighow, said there's been no talk of Parnell asking Therriault to resign.
