US President Donald Trump and his White House challenger Joe Biden are feuding over plans for their final TV debate.
The Republican president’s campaign accused organisers of Thursday’s showdown of helping the Democrat by leaving out foreign policy as a topic.
The Biden camp shot back that Mr Trump was trying to avoid questions about his response to the coronavirus pandemic.
With two weeks to go until the election, Mr Biden is said to have a commanding lead nationally in opinion polls.
However, he has a smaller lead in the handful of key US states that will ultimately decide the outcome.
The president’s camp sent a letter to the Commission on Presidential Debates calling for topics to be adjusted for the final primetime duel this Thursday.
Trump campaign manager Bill Stepien said in the letter that the campaigns had already agreed foreign policy would be the focus of the third debate.
The topics were announced by moderator and Kristen Welker last week: American families, race in America, climate change, national security, and leadership.
