Tough call but I'm sticking with my original assessment because of what I see below the loop of the "R". I see no round character. Just a short line. But you may be right. How soon before all photographers are banned from the White House?
With apologies to Shakespeare and Richard III;
Some focus! Some focus! My kingdom for some focus!
The more I look at it I don't think it's Rice > BB
What would Rice have to with it?
It's about a phone call from the Pres. to Netenyahu.
It looks like 3 letters, Pre or Prs - abbreviation for President.
So it's Pre > BB > DNR
from Update 5 at the original story link...
Update 5. More people concur, the notes in Biden’s hand pertain to the phone convo with Netanyahu – not benghazi. There is a time of 6:2(?) written in his notes. This could be a Benghazi convo immediately following that phone call. (*off subject* funny how the media never reported Biden was on the phone — propping up inept Obama?)
