World leaders conveyed congratulatory messages in the face of President Donald Trump's refusal to concede the election. On Saturday, Trump said that the contest is "far from over," baselessly alleging widespread voter fraud and vowing to take legal action.
Trump's team of lawyers is expected to focus on the states of Pennsylvania, Michigan, and Georgia, where the final tally was close. Over the past several days, the current commander-in-chief has repeatedly declared himself the winner, despite evidence to the contrary.
According to Jim Acosta, the chief White House correspondent for CNN, sources close to Trump claim that his lawyers have "nothing concrete" in regard to electoral fraud.
