Conduct this investigation and bring those responsible for these despicable acts to justice. We have to unify. We have to come together and send one very clear, strong, unmistakable message that acts or threats of Political Violence of any kind have no place in the United States of america. So far the devices have been what appear to be a pipe bomb. What we saw here today was an effort to terrorize. This clearly is an act of terror, attempting to undermine our free press and leaders of this country through acts of violence. Through acts of violence. With me now with the latest nbc news investi...
