WASHINGTON -- Gen. Mike Flynn provided the first scalp in the Trump administration in record time -- he served as White House National Security Adviser for 23 fleeting days before he resigned Monday night. In the eyes of President Donald Trump, Flynn could be his team's first casualty of "fake news." As Trump told reporters at his epic press conference Thursday, he asked for Flynn's resignation because Flynn didn't tell Vice President Mike Pence that he may have discussed sanctions with the Russian ambassador during the transition period.
