Politico: Biden swore at Trump behind closed doors. In a conversation with longtime friends and aides, Biden described Trump as a “sick bastard,” the publication says.

Such antics contradict Biden's image as someone who gives the impression that he is seeking to reduce the "level of harshness" in politics, the newspaper writes. At the same time, the president's intemperance shows a "deep-seated anger" towards Trump, with whom Biden may yet have to compete again.
