From Friends of Sean:

Sean is currently facing increased scrutiny and repression from the ODRC in retaliation for his published writings, including loss of privileges and a possible increase in security status. 

On October 1, 2018, Sean ended a 29 day hunger strike. It is no longer necessary to call in to the prison, but it would be a great time to send Sean warm words of encouragement as he recovers from his strike. If you’d like, you can include a couple embossed envelopes in with your letter, available at the post office.
