On April 25, 2019, Biden announced his candidacy in the 2020 presidential election. He became the presumptive Democratic nominee in April 2020 and reached the delegate threshold needed to secure the nomination in June 2020. Biden and his running mate Kamala Harris defeated incumbent president Donald Trump and vice president Mike Pence in the general election. Biden is the oldest elected president, the first from Delaware, and the second Catholic. His early presidential activity centered around proposing, lobbying for, and signing into law the American Rescue Plan Act of 2021 to help speed up the United States' recovery from the economic and health effects of the COVID-19 pandemic and the ongoing recession, as well as a series of executive orders. Biden's orders addressed the pandemic and reversed several Trump administration policies, including by rejoining the Paris Agreement on climate change, reaffirming protections for Deferred Action for Childhood Arrivals recipients, halting construction of the Trump border wall, ending the Trump travel ban imposed on predominantly Muslim countries, and revoking permits for the construction of the Keystone XL pipeline.
