White House press secretary Karine Jean-Pierre and national security adviser Jake Sullivan will hold a briefing with reporters Monday afternoon and are expected to preview the U.S.-Africa Leaders Summit that begins Tuesday.

President Biden has invited 49 African heads of state and the African Union Commission chair to Washington, D.C., for the three-day summit. The leaders are expected to talk about the coronavirus, climate change, trade, the impact of Russia’s invasion of Ukraine on Africa and more.
