US President Joe Biden announced on July 22nd local time a new decision: after declaring his withdrawal from the 2024 US presidential election, he will participate in Vice President Kamala Harris's campaign activities. This statement has sparked widespread attention within political circles. At the same time, facing pressure from some members of the Republican Party demanding that Biden step down immediately, Biden emphasized that he would continue to dedicate himself to national affairs for the last few months of his presidency, fulfilling his duties responsibly. Biden's move not only demonstrates his strong support for the Democratic Party but also reflects his deep understanding and strategic approach to the current political situation in the United States.
