According to ChainCatcher, the first candidate TV debate for the 2024 US presidential election took place at around 9 p.m. local time on the 27th (around 9 a.m. Beijing time on the 28th). The current president, Democrat Biden, and the former president, Republican Trump, who had been engaged in a "war of words" in the air, took the stage again after nearly 4 years. According to ABC, Biden and Trump did not shake hands at the beginning of the debate. The media said that this seemed to break tradition, but there have been cases where the two debaters did not shake hands before. For example, during the 2020 epidemic, the two of them did not shake hands when they debated. Trump did not shake hands when he debated with Hillary in 2016.

U.S. President Joe Biden and former President Donald Trump opened their first presidential debate with an economic attack, with each candidate blaming the other for rising grocery and housing costs. Voters see the economy as one of the defining issues of the campaign. Polls show that despite strong job growth and manufacturing and infrastructure investment, voters are skeptical of Biden's record as historically high inflation hits American households. "Our economy is in free fall and the pandemic was handled so badly," Biden accused Trump of saying. Biden promised to do more to address the high cost of household goods and housing, an issue that has contributed to voters' low ratings of his handling of economic issues. Trump defended the tax cuts, which are set to expire next year, saying they paved the way for a stock market boom.
