Biden is also expected to announce that Tim Lenderking has been tapped to be the U.S. envoy to Yemen, a source familiar with the decision tells NBC News, placing a longtime career diplomat in an important senior position as the US announces an end to American support for offensive operations there.

Secretary of State Blinken described Yemen as “the worst humanitarian situation in the world,” and has said he will prioritize reviewing the Trump Administration’s last minute foreign terrorist designation of the Iran-backed Houthi rebels, which international organizations say only exacerbates the humanitarian crisis on the ground by blocking the delivery of critical food and aid.

In addition to the order on Yemen, Biden is expected to announce a number of policy actions aimed at undoing Trump’s agenda.

He will order ordering a freeze on the withdrawal of U.S. troops from Germany initiated by Trump and he will issue a memorandum protecting the rights of LGBTQ individuals around the world.
