Presidential electors coast to coast are casting the votes that will choose Joe Biden as America’s next president, a formality that has taken on added importance this year because of President Donald Trump’s refusal to concede he lost his race for reelection. The Associated Press reports that with heightened security in place in some states, Democratic electors in the key battleground states of Arizona, Georgia, Nevada, and Pennsylvania gave Biden and Vice President-elect Kamala Harris their votes Monday in low-key proceedings. The results will be sent to Washington and tallied in a Jan. 6 joint session of Congress over which Vice President Mike Pence will preside. Trump has refused to concede the election and continues to make unsupported allegations of fraud.
