President-elect Joe Biden. Susan Walsh/AP Biden plans to sign "roughly a dozen" executive orders that include rejoining the Paris climate accord, and reversing the travel ban on several majority Muslim countries. A memo from incoming chief of staff Ron Klain outlines Biden's 10-day action plan in which he hopes to immediately reverse some of President Trump's signature policies. Biden has inherited a number of crises, including the COVID-19 pandemic, the resulting economic crisis, a climate emergency, and a racial equity crisis. He plans to tackle the COVID-19 pandemic first and on his first day in office will order mask-wearing mandatory on all federal property and during inter-state travel.
