President Trump attacked New York Times reporter Maggie Haberman on Twitter Saturday — which happened to be Haberman's daughter's birthday, she told CNN's Chris Cuomo and Alisyn Camerota on Monday's New Day. Trump was reacting to an article Haberman co-wrote about Trump's reportedly abusive treatment of lawyer/fixer Michael Cohen and speculation on whether Cohen would flip on Trump if prosecutors threaten him with a long jail term. Trump's tweets drew special scrutiny because of the bizarre Haberman attack and because it wasn't clear who he was calling a "drunk/drugged up loser" — Haberman guessed it was Sam Nunberg, not Roger Stone, because Trump is "too aware of what Stone could do to him to be that direct" and has been scared of Stone "for years." The topic is clearly "hitting a nerve" with Trump, and he and his legal team "are very anxious" about the Cohen investigation, Haberman said on CNN. "The story was really not about destroying their relationship — the president has destroyed their relationship pretty handily on his own over a long period of time," Haberman said.
