david corn, of course, heidi pryzbilla and seth waxman, thank you for your various contributions to this-year-old discussion. the other big story of the day, president trump called off his summit with north korea. what have now? we'll find out whether kim jong-un is really wanting to make a deal with us or whether they want to play with us. plus, the nfl caves to trump vowing to find teams whose players kneel during data national anthem. for some players and former players it's a decision that hits them as un-american. we'll talk to one of them tonight. and trump's tribalism. he's willing to tear down the institutions of this country and stir it up distractions as his way of shielding himself from justice. he's using this, taking issue on that front. it's all about the rule of trump, not the rule of law. he wants people taking sides. tribally preferably. finally let me finish tonight with trump watch. this is "hardball." or plan for tomorrow?
