Presidents John Adams, John Quincy Adams and Ulysses S. Grant did not attend the inauguration of the incoming president, according to the White House Historical Association.”To all of those who have asked, I will not be going to the Inauguration on January 20th,” Trump wrote in a tweet, the third message from his account since blocked from Twitter for 12 hours on Wednesday.Biden’s victory was projected by all major news outlets in mid-November and confirmed by Electoral College votes in mid-December. The Republican president has falsely insisted he won in a “landslide,” asserting his reelection was stolen through massive electoral fraud.His refusal to accept the election results culminated in a deadly riot on Wednesday, when swarms of his supporters stormed the U.S. Capitol and derailed congressional proceedings to tally electors’ votes and confirm Biden’s win in the Nov. 3 election.Trump’s decision to not attend Biden’s inauguration comes one day after he conceded the presidential election. In a nearly three-minute video posted on Thursday, Trump, without mentioning Biden by name acknowledged that “a new administration will be inaugurated on January 20th.””Now tempers must be cooled, and calm restored. We must get on with the business of America,” Trump said in his first address to the nation following the riot that left five people dead, including a Capitol police officer.”My focus now turns to ensuring a smooth, orderly and seamless transition of power,” the president added.
