The new president signed the orders just hours after taking the oath of office at the Capitol, pivoting quickly from his pared-down inauguration ceremony to enacting his agenda. With the stroke of a pen, Biden ordered a halt to the construction of Trumpâs US-Mexico border wall, ended the ban on travel from some Muslim-majority countries, declared his intent to rejoin the Paris Climate Accord and the World Health Organization and revoked the approval of the Keystone XL oil pipeline, aides said.
