TUCSON (AP) - TUCSON, Ariz. (AP) — Protesters continue to follow Donald Trump to his campaign stops. Both in Phoenix and Tucson, Arizona yesterday, protesters tried to intervene. They blocked the main road into his outdoor Phoenix rally for several hours before it started, and interrupted him in Tucson before being thrown out. Trump was talking tough on immigration. Fellow Republican John Kasich is ruling out becoming anyone's running mate. Democrat Bernie Sanders also campaigned in Arizona while Hillary Clinton visits tomorrow ahead of Tuesday's primary.
