The rise and fall of Trump's relationship with Mika Brezinski, the 'Morning Joe' co-host he just attacked on Twitter

Evan Agostini/APMika BrzezinskiPresident Donald Trump made news on Thursday morning when he viciously attacked MSNBC host Mika Brzezinski on Twitter, calling her "low I.Q. Crazy Mika" and said she was "bleeding badly from a face-lift."

Brzezinski shot back at the president on Twitter, posting a photo of a box of Cheerios that showed a child reaching for the cereal with the words "Made For Little Hands" printed across it.

Trump has long taken issue with accusations that his hands are small. Brzezinski called the president's hands "teensy" during her show, "Morning Joe," on Thursday morning.
