A group of about 20 local DC area people, who are affiliated with the Bradley Manning Support Network,arrived at the DNC headquarters to meet with a representative of the Obama 2012 campaign to deliver our letter with our concerns for Bradley Manning. We were met at the main entrance of the DNC by security who refused entrance to about 4 people from the group who wanted to go inside and deliver our letter and to request that it be faxed to President Obama. The security guards told us to get off the front steps as were on private property. We explained that we were there on business. They refused us entry. We said we would not leave. Police were called. US Capitol Police showed up in four police cars and one police wagon.
