Biden’s southern border czar Roberta Jacobson to step down at the end of April

• Jacobson’s departure comes after there were more illegal border crossings in March than in any single month in 15 years on top of record numbers of unaccompanied minors overwhelming government immigration and shelter systems.

Between the lines: Jacobson has appeared at the White House podium to explain the situation at the southern border and the administration’s efforts to manage it.

• Just more than two weeks ago, she and other top administration officials met with Mexican officials to address ways to stem the flow of migration to the U.S.-Mexico border.

What they're saying: "Ambassador Roberta Jacobson's leadership in serving as the Special Assistant to the President and Coordinator for the Southwest Border at the National Security Council has been an invaluable contribution to the Biden-Harris Administration and to the United States," National Security adviser Jake Sullivan said in a statement Friday.
