Keith's note: In other words news media will not be allowed to interact directly with Holdren or Bolden or anyone else. Questions will be screened by NASA PAO before the are asked. In other words: do no expect any news. This is called "running out the clock" here in Washington. In the waning days of an administration you say only what you want to say and make it all but impossible for anyone to dispute what you say. But you make it look like you are saying something because innocuous, safe questions are asked.
