President Donald J. Trump is reportedly “seething with envy” and “furious” that another baby is suddenly getting all the attention, White House aides have confirmed. The aides, speaking on condition of anonymity, said that Trump was “beside himself” after watching cable news cover a baby other than himself all Monday morning. “He can’t understand why they are suddenly obsessed with this baby,” one aide said. “He thinks he should be the only baby that people are thinking about, and this new baby is driving him nuts.”
