Trump has ordered the U.S. to withdraw from the U.N.’s World Health Organization, a move health experts say could undermine the global response to the next pandemic.

Other executive orders issued by Trump on day one include a rollback of policies around DEI and LGBTQ rights, reflecting the mounting right-wing attack on transgender communities. One order states, “Agencies will cease pretending that men can be women and women can be men when enforcing laws that protect against sex discrimination.”

Another order seeks to rename the Gulf of Mexico to “Gulf of America” and Alaska’s Denali, the highest peak in North America, to Mount McKinley — the name it was known by until President Obama changed it in 2015. The order has no bearing on what names are used for the sites internationally.

Trump also reversed a Biden executive order barring the use of deadly chokeholds and no-knock warrants by federal law enforcement, and a Biden order that sought to wind down the Justice Department’s use of private prisons.

Trump also revoked Biden’s removal last week of Cuba from the U.S. state sponsors of terrorism list.
