PROBLEM: Bush as president occasionally phoned Clinton
 George W. Bush had a special phone friend during his White House years: Bill Clinton.
 Asked on CBS television's "Face the Nation" whether it was true that he often called Clinton  Bush replied: "I don't know about often  but I did. I called him. He didn't call me because he knows how busy a president is. I called him and we chatted on occasion."
 "I was always pleased when he called me " Clinton said as he sat beside Bush for the interview. "I make it a practice never to bother the president. I don't call President Obama either. ... They got plenty to do."
Neither Republican Bush nor Democrat Clinton said just what they discussed.
 "I was always pleased when he called me " Clinton said as he sat beside Bush for the interview. "I make it a practice never to bother the president. I don't call President Obama either. ... They got plenty to do."

 "I was always pleased when he called me " Clinton said as he sat beside Bush for the interview. "I make it a practice never to bother the president. I don't call President Obama either. ... They got plenty to do."
 Bush's eight years in office followed Clinton's two terms. While poles apart politically  the ex-presidents said they consider themselves to be friends.
 "We have developed a very honest  good friendship " Clinton said. "And we've made our disagreements respectful and we've had a good time doing it."

PROBLEM: White House aide Stephen Miller – who  really  just looks like an obnoxious guy – made a Sunday appearance on CNN’s “State of the Union ” with Jake Tapper.
 Miller  was brought on to defend some of President Trump’s statements  but it became clear pretty early on that  he  was sent to the network with a mission of playing court jester and administration fool on live TV.
As Tapper attempted to get through a line of straight questioning   Miller  lurched into a babbling filibuster  avoiding anything resembling replies  and opting to simply use the annoyingly childish vernacular of the Trump Twitter feed to describe CNN.
 Miller  spent a good portion of the interview defending Trump and bashing the network  and Tapper eventually cut  him  off  suggesting Trump was the only viewer  Miller  cared about. “I think I’ve wasted enough of my viewers’ time. Thank you  Stephen ” Tapper added as he ended the interview.
Tapper was right  of course. I’m going to say it’s a very safe bet that  Miller  was briefed before the appearance to be as combative and uncooperative as possible  no matter what the questions.
 Miller  had been instructed on how to behave during the interview  but  he  apparently wasn’t sure of what to do in the event the interview was stopped early  so  he  just decided to hang around.
Yup.  Stephen Miller  attempted a sit-in on the CNN set  or something equally idiotic.
 Miller  was asked to leave the set multiple times but refused to leave  after which  he  was escorted out by security  a CNN employee confirmed to The Hill.
