Incoming White House chief of staff Ron Klain has already listed some of Biden’s priorities. They include reintroducing protections for “Dreamers” brought to the country illegally as children and a slew of environmental regulations.

Biden would also ensure the United States rejoined the Paris agreement and the World Health Organization, Klain told MSNBC. He would roll back the travel restrictions President Trump placed on a handful of majority-Muslim countries. And fix “some of the flaws in the Affordable Care Act that the Trump administration has imposed,” Klain said.

Biden’s COVID-19 response plan and broader immigration reforms were on top of his to-do list too, according to Klain.

“He’s getting ready for that now during the transition. We’re going to deliver on that starting on Jan. 20,” he said.
