Another potential White House loss

Three sources with direct knowledge tell me White House Staff Secretary Rob Porter — regarded as one of the biggest brains in the building — has received overtures from major companies and organizations wanting to poach him from the Trump administration.

I'm told Porter has not yet seriously entertained an offer, and has made no decisions about his future. Top White House officials are keen to keep him in the building.
