Mika Brzezinski, one of the targets of President Donald Trump's angry morning tweets, is clapping back at Trump in a tweet of her own. This morning, Trump referred to Joe Scarborough's Morning Joe co-host (and fiancée) as "low I.Q. Crazy Mika" (which is not very catchy, as far as nicknames go). So, in response, Brzezinski tweeted a picture of the back of a Cheerios box that reads "Made For Little Hands."
