Vice President Kamala Harris told NBC News that her team is preparing for the possibility that Trump will declare himself the winner, even if the results are not yet settled.

Vice President Kamala Harris, her campaign team and some of Donald Trump’s own allies say they expect the former president to quickly declare victory on election night — even if the outcome is not yet settled in key swing states.

Between the time it takes to process mail ballots and deal with provisional ballots in some battleground states, votes will not be fully tabulated on election night. Projections of who won a close presidential race might not come for days, similar to the 2020 election.

NBC News spoke to four Trump allies, all of whom speculated that the former president may be prepared to pull a repeat of 2020 and quickly declare he is the victor on election night when that is not yet certain. The sources all noted they did not have direct knowledge that this was a formal Trump campaign plan.
