Now for an update on the hunger strike happening in California prisons. 

The protest over the long-term isolation of inmates is now in its fourth week, with more than 500 prisoners are still refusing food.

On Tuesday, the federal receiver in charge of prison medical care sent a team to Corcoran State Prison in the San Joaquin Valley to check on the overall health of the prisoners.

Joyce Hayhoe, Director of Legislation and Communications for California Correctional Health Care Services, joins the show. She was also part of the team that visited Corcoran.
