Barr will show up, continue to lie and obstruct. It wins more time for a man who realizes his best chances will be in an impeachment hearing rather than arrest for ultimately ignoring a subpoena. The Trump administration is not about governing, it is about obstruction while they use the power of the USA for their own purposes. Those purposes are not benign to the sovereignty of the USA. The Former Special Council Robert Mueller knows that, too. That is why he wrote Barr immediately after the fraudulent 4 page letter. I can't believe that letter had to be leaked a month later in order to save the US Constitution from potential demise.
