President-elect Joe Biden is set to formally introduce his national security team to the nation, building out a team of Obama administration alumni that signals his shift away from the Trump administration’s “America First” policies and a return to US engagement on the global stage.

The picks for national security and foreign-policy posts include former secretary of state John Kerry to take the lead on combating climate change.
