I already knew Donald Trump was a liar. Most of the country believes that, but to see these two men testify to it was about as damning of a political moment as I've ever seen in my 30 years of following politics. Dan Rather, now 85 years old, said of Monday's developments: "If you are a praying person, today is a day to pray for the future of your country. I have seen a lot in my decades in the press, but I have never seen a day like this. This is a stress test for our democratic institutions and one can only hope that the system of checks and balances we hold so dear, can indeed hold."
