From Politico:
In less than two months since entering the 2012 race, Bachmann’s campaign staff has become embroiled in at least five unusually hostile encounters with the traveling media marked by pushing, shoving and, in one instance, the allegation of a threat of violence to a reporter. …
The campaign makes no apologies for its physically aggressive approach to media management, asserting that it is simply doing what it has to do to protect a popular, controversial candidate. The most aggressive aide — a tall, silver-haired man according to reporters — a spokeswoman said, is a former Secret Service agent who has guarded presidents. He and an advance woman frequently make physical contact with reporters.
“The No. 1 priority for us every single day we step out on the campaign trail is the safety and security of Michele Bachmann,” said her spokeswoman, Alice Stewart.
