That's the whole point. He said he suspended his campaign this week out of respect for President Reagan. So why was his press pool following him?
Because he's the presumptive Democratic presidential nominee who likes to do stupid things when he's not campaigning. The press followed him on his Sun Valley "vacation" -- That's where he arrogantly told the pool reporter "I don't fall. That S.O.B. knocked me over" when the secret service agent protecting him allegedly cut him off. The press is still following him now. As they should be.
