President Donald Trump is set to speak at the Conservative Political Action Conference today after announcing he is replacing Chairman of the Joint Chiefs of Staff General C.Q. Brown and will soon swap out five other high-level positions in an unprecedented shake-up of the leadership of the U.

On the foreign policy front, Trump is ramping up his attacks on Ukrainian President Volodymyr Zelenskyy after calling him a "dictator" and falsely blaming him for starting the war with Russia. Trump said on Friday he's had "good talks" with Russia's Vladimir Putin but not Ukraine, who he said has "no cards" as negotiations unfold.
