1. I grant in part and deny in part Valerio's motion to amend complaint (Doc. No. 49). The motion is granted to the extent Valerio seeks to assert a First Amendment claim against defendant CO FNU Marissa and CO FNU Sauerhaben. The motion to amend is otherwise denied;

3. The clerk's office is directed to docket Valerio's Proposed Second Amended Complaint (Doc. No. 49-3) as the Second Amended Complaint, as if filed on the date of this Order approving the October 2017 Report and Recommendation; and

4. The magistrate judge is to direct service of the Second Amended Complaint upon defendants Marissa and Sauerhaben.
