Greg Corombos of Radio America and Jim Geraghty of National Review fume over Russia’s blatant provocation of a U.S. Navy ship in the Baltic Sea and in the Obama administration’s pathetic response.

And they discuss Karl Rove and many deep-pocketed donors preparing to help Trump, mainly to deny Hillary Clinton the presidency.
