U.S. President Donald Trump says he's spoke with Russian President Vladimir Putin and that the Russian leader told him “very strongly” that he will respond to Ukraine’s weekend drone attack on Russian airfields.

Trump previously said his personal relationship with Putin would usher in peace for Ukraine. Now, he says Putin's gone "absolutely CRAZY!"
