"After Bush campaign bouncers handled the evictions, Secret Service agents, accompanied by Bush's personal aide, supervised the arrests and detention of the activists and blocked the news media from access to the hecklers.
The Bush campaign has made unprecedented efforts to control access to its events. Sometimes, people are required to sign oaths of support before attending events with Bush or Vice President Cheney. At times, buses of demonstrators are diverted by police to idle in parking lots while supporters are waved in. And the Secret Service has played an unusual role; one agent cooperated with a plan by the Bush campaign last month to prevent former senator Max Cleland (Ga.), a Kerry ally, from handing a letter to the agent outside Bush's Texas ranch."
