Historian Michael Beschloss rips Trump for ‘deliberately undermining legitimacy of an American presidential election’

During the briefing, Trump attacked voting by mail, argued that voter I.D. is necessary and even warned that we may never know who wins the election.

NBC News presidential historian Michael Beschloss summed up the message of the press conference.

"President of the United States is deliberately undermining legitimacy of an American presidential election," Beschloss summarized.
