President Biden signed 17 executive orders Wednesday in his first official act from the Oval Office. Among other things, the orders strike down Trump’s ban on travelers from majority-Muslim nations, end construction of Trump’s border wall and strengthen DACA, the Deferred Action for Childhood Arrivals program for young immigrants.

Biden rejoined the Paris climate accord and canceled the Keystone XL pipeline, put a moratorium on oil and gas permits in the Arctic National Wildlife Refuge and ordered a review of Trump’s actions undermining public health and the environment.

Biden extended a federal moratorium on evictions and a pause on student loan payments and interest. He also ordered the U.S. to reengage with the World Health Organization and ordered a mask mandate for interstate travelers and visitors to federal buildings during the pandemic.
