How Biden and Trump are talking about COVID as they campaign

Americans again headed to the polls Wednesday, even as coronavirus continued its nationwide surge. On the campaign trail, President Trump and Sen. Kamala Harris visited Arizona, a state Trump won by 3.5 points in 2016. Current polls indicate the race in the battleground state could be closer this year. Meanwhile, Joe Biden cast his own ballot in his home state of Delaware. Lisa Desjardins reports.
