PolitiFact is live fact-checking the first 2024 presidential debate Sept. 10 in Philadelphia between Vice President Kamala Harris and former President Donald Trump.

PolitiFact has fact-checked Harris 55 times since 2012 and Trump 1,050 times since 2011. Tonight, we’ll draw on that deep archive to check the accuracy of the candidates’ statements.

PolitiFact fact-checks statements of people in power, regardless of political party. This is how we choose claims to check.
