WILMINGTON, United States (AFP) — United States (US) presidential candidate Donald Trump on Saturday rejected a proposal from Democratic opponent Kamala Harris to face off in another debate, saying it was “too late” to do so.

“The problem with another debate is that it’s just too late, voting has already started,” the Republican said at a rally in North Carolina, with early voting already underway in three states.

Kamala Harris challenged Donald Trump to another debate with her campaign saying she had accepted an invitation from broadcaster CNN to host the event on October 23.

“Vice President Harris is ready for another opportunity to share a stage with Donald Trump,” her campaign chair Jen O’Malley Dillon said in a statement.

“The American people deserve another opportunity to see Vice President Kamala Harris and Donald Trump debate before they cast their ballots.”

Republican Trump has attended two debates so far, one against President Joe Biden and one against Harris, who has since replaced her boss at the top of the Democratic ticket.

Most pundits put Harris as the winner of the last debate, which was held on September 10.
