Trump says Obama underestimated him

Obama returned to the campaign trail on Wednesday, launching a blistering attack on Donald Trump with less than two weeks to go before the Republican president's Election Day face-off with Democratic nominee Joe Biden.

Trump also referenced his interview with 60 Minutes this week, telling his supporters "we have a little surprise" for the CBS news program.

The last days of campaigning are taking place amid a surge in new cases of COVID-19 and hospitalizations in battleground states, including North Carolina and Pennsylvania but also Wisconsin, Ohio, and Michigan.

Polling shows a majority of voters are disappointed in the way Trump has handled the pandemic, which he has repeatedly said would disappear on its own.

Biden and Trump are scheduled to meet in their second and final debate on Thursday night, giving the Republican an opportunity to change the trajectory of a race that Biden is leading in national polls.
