Yep.  Mr/Ms  Milbank exposes his motives at the end when he compares politics to "tribalism". This is exactly the reason people don't trust the media for getting  fair and balanced news anymore. Their bias is as clear as  creek water.  If Obama had done the same thing the media would be showering him and the D's with praise for being 'above' party politics.  But Trump does it and  its  "Look at that!  He talk with the  enemy!  Start beating  war drums!"   
.
Republicans have never been against working with their colleagues in Congress, but the D's  just haven't been willing to help until now.  Why is that?  Could it be that  the mid-term elections are coming into view now?
