Story highlights Trump tweeted about his victory on Wednesday, praising himself for focusing on the Electoral College

He criticized his opponent Hillary Clinton, who won the popular vote, for running a bad campaign

(CNN) The new year is quickly approaching, and with it, a new administration that must face terror and other challenges around the world. But on Wednesday, President-elect Donald Trump was looking back to his upset victory in the 2016 campaign, still eager to rebut naysayers who've criticized him for losing the popular vote.

Trump tweeted on Wednesday morning, "Campaigning to win the Electoral College is much more difficult & sophisticated than the popular vote. Hillary focused on the wrong states!"
