Sullivan credited Jacobson with shaping the U.S. relationship with Mexico and launched efforts to work with El Salvador, Guatemala, and Honduras to improve conditions on the ground.
Just last month, Biden announced that he was putting Vice President Kamala Harris in charge of diplomacy in the region known as the Northern Triangle.
Biden has tried to keep his government’s focus on fighting the coronavirus and reviving the economy, but problems at the border have increasingly taken center stage and even some of his allies have criticized him, particularly over the treatment of unaccompanied children who have been housed in crowded facilities.
Republicans accuse Biden of pushing through policy changes that have fueled the increase in migrants at the border and not being able to deal with them once they’ve arrived.
The news of Jacobson’s departure comes a day after the administration announced that it saw a sharp increase in migrants attempting to cross the border in March, including a record number of unaccompanied children taken into custody.
More than 18,800 unaccompanied children crossed the border in March, a record-breaking figure; the previous high was more than 11,000 children in May 2019. The March numbers represent an almost 100 percent increase from February, when more than 9,400 minors were taken into custody.
In early March, Jacobson appeared at a White House briefing to discourage migrants from traveling to the United States. But she misspoke when speaking Spanish, saying the border was open when she meant to say it was closed.
