In a related development as reported earlier, Joe Biden is planning to address the nation in his home state of Delaware.
Some aides had suggested he might declare victory if more states were projected in his favour, pushing him over the 270 electoral college votes needed to clinch the presidency.
Sources have told CBS News that Biden will speak regardless of the fact that news outlets may not be able to add to his tally, given slower-than-expected vote counting.
Biden leads in the battleground states that are crucial to reaching the White House: Pennsylvania, Nevada, Arizona and Georgia. END
