Video: Ebola Press Conference Turns Tense, Dallas Mayor Scolds Members of Press

The atmosphere turned tense during a press conference on the first patient diagnosed with Ebola in the United States after Dallas Mayor Mike Rawlings lectured reporters for helping create "disorganization" and Centers for Disease Control and Prevention officials declined to answer some questions.

"Just know, you will have a moment to be part of the problem or part of the solution. Because it is, at best, disorganized out there and we have some members of the press that are creating a bit more of it. I know that's hard for you to imagine, but need everybody to be professional at this point,” the mayor said. "Safety is first and foremost."

As officials left the presser, one reporter apparently complained about the “transparency” being shown in the Ebola case.

"Seriously, is this transparency if you get us all here and then walk away after a half dozen questions?” the reporter said, adding, “Even a half an hour isn't enough. ... I have a job too. You guys are not being forthcoming.”

CDC Director Tom Frieden said previously officials want to be careful not to disseminate inaccurate information and vowed to "give you all the valid information we have as soon as we have it."
