(CNN)President-elect Joe Biden has pledged to reassert the United States' leadership role on the global stage through a series of day-one executive actions that would mark a drastic turn from outgoing President Donald Trump's policies.

Now that Biden has defeated Trump, his transition team is beginning to turn his campaign-trail promises into plans he can implement early in his presidency.

Biden's first focus is likely to be the worsening coronavirus pandemic. He is set to name a 12-person coronavirus task force on Monday, two sources with knowledge of his plans said. Biden also said during the campaign that he will speak with Dr. Anthony Fauci, the government's top infectious diseases expert, before taking office.
