Lee suspended Mirkarimi after the sheriff pleaded guilty to domestic violence charges stemming from a dispute with his wife on New Year's Eve. San Francisco's Ethics Commission is now determining whether Mirkarimi can return to his job.
Mirkarimi's camp has accused Lee of trying to push the sheriff toward another job, either in government or the private sector.
"You know, I've told the truth to the Ethics Commission and I'll continue doing that if called upon," Lee said.
Mirkarimi's attorney plans to issue subpoenas to appear before the Ethics Commission for four people who say Lee consulted with them before he suspended the sheriff.
