Later Tuesday, demonstrators will be outside of Central Arizona Shelter Services, or CASS, to protest the Department of Veterans Affairs' decision not to renew a grant it had been giving to CASS.

The money comes from the Veterans Affairs Grant Per Diem program and pays for veteran-specific needs at the shelter.

Joining us now to talk about this program and what the loss of funding means is Mark Holleran, CEO of CASS.
