Jim Geraghty of National Review and Greg Corombos of Radio America enjoy watching U.S. Ambassador to the United Nations Nikki Haley stand her ground after chief Trump economic adviser Larry Kudlow suggests Haley was confused about whether new sanctions had been ordered against Russia.  They also shudder as more horrible allegations come out against disgraced Missouri Gov. Eric Greitens, and because he won't resign even after top GOP leaders urged him to step down.  They roll their eyes as independent 2016 presidential candidate Evan McMullin remains mired in campaign debt and has missed his last three required filings with the Federal Elections Commission.  And Jim and Greg pay tribute to the remarkable life of former First Lady Barbara Bush.
