IMPEACHMENT/JOE BIDEN/TRUMP AS PRESIDENT: “The cascade of tweets began at 4:56 a.m. on May 1, starting with the president’s criticism of the nation’s largest firefighters union’s endorsement of Joe Biden. Over the next two hours, more than 60 retweets bashing Biden and the firefighters’ decision would follow from Donald Trump’s Twitter account. The burst of activity came during a three-month period that reveals an extraordinary preoccupation with his potential general election rival, and provides a window into Trump’s thinking in the run-up to his fateful July 25 call with Ukrainian President Volodymyr Zelensky. At home and abroad, on Twitter, at campaign rallies, in interviews and even from the White House lawn, Trump spent an inordinate amount of time deriding Biden and insisting that the former vice president could not be ahead of him in polls — despite the fact that Biden has led the president in general election matchups in every major poll conducted in 2019.”
