Questions emerge over presidential debate moderator Kristen Welker

President Donald Trump says Kristen Welker, the moderator of the upcoming presidential debate, is a "radical Democrat" who will not be a fair arbitrator between himself and his Democratic challenger, Joe Biden.

President Trump's comments come after revelations Ms Welker was a registered Democratic voter while being employed by NBC as a White House correspondent.

The third and final TV debate will take place in Nashville, Tennessee on 23rd of October (Australian time), and will be the final time the two candidates square off directly before the presidential election.
