Democratic presidential nominee Joe Biden says he has tested negative for COVID-19 ahead of his debate with President Donald Trump.

Biden made the comments to reporters in Wilmington, Delaware, on Thursday before flying to Nashville, Tennessee, where he's scheduled to participate in the second debate with the Republican president, the final scheduled meeting of the two candidates before the Nov. 3 election.

Biden says he underwent the coronavirus testing on Thursday.

Trump seems confident, court to end 'Obamacare'

President Donald Trump says ``it will be so good'' if the Supreme Court puts an end to the Obama-era health law when the justices hear challenges to the Affordable Care Act next month.

Trump made the comment in an interview with CBS' ``60 Minutes'' that's set to air Sunday night.

The president posted the full, unedited interview on Facebook on Thursday. Democrats argue that Republicans are counting on the Senate confirmation of Trump nominee Amy Coney Barrett to the Supreme Court to be the death knell of the law, which is also called ``Obamacare.''
