Poor Joe Biden. He can't seem to catch a break. Even with extremely Democrat-friendly news host George Stephanopoulos, the pressure of a simple question and its follow up were far too much for Biden to handle. He got caught in a bald-faced lie, then lied about the original lie before going into some incoherent rant about President Trump.
Stephanopoulos asked Biden whether he knew about the investigation into General Michael Flynn that began when Biden was still Vice President. He replied by saying, "I knew nothing about those moves to investigate Michael Flynn."
Unfortunately for Biden, that's an old talking point. It has been revealed through declassified testimony that Biden was present in meetings pertaining to the Flynn investigation. Both he and President Obama held briefings over the supposed Russian hack of the 2016 election in January, 2017. Attendees testified that Biden and Obama discussed General Flynn in-depth.
This is not the first time Joe Biden was caught lying while also having a senior moment. Should be a fun campaign if he ever emerges from the basement.
