FILE - In this Jan. 20, 2017, file photo President Donald Trump and Vice President Mike Pence listen to the National Anthem sung by Jackie Evancho with former President Barack Obama and his wife Michelle during the 58th Presidential Inauguration at the U.S. Capitol in Washington. Obama, who invited Trump to the White House soon after Trump's election four years ago and pledged cooperation in the transfer of power, is not shocked that a man who “never admits loss” is refusing to acknowledge defeat now.
