"President Biden on his first day in office took a range of executive actions, including implementing a national mask mandate on federal property, revoking a permit for the Keystone XL oil pipeline and reversing a travel ban from several largely Muslim and African countries, officials said.
Coming after Mr. Biden was inaugurated as the 46th president in a midday ceremony, the actions are intended to signal a more aggressive approach to the coronavirus pandemic and end some of President Trump’s key policies while setting the agenda for the next four years." - The Wall Street Journal
