Biden's border coordinator stepping down at end of the month

President Joe Biden's border coordinator is stepping down at the end of the month, the White House announced Friday -- an unusual time given the administration is dealing with record numbers of unaccompanied migrant children at the US southern border.

Roberta S. Jacobson was appointed as a special assistant to the President and was a key official dealing with the surge of migrants at the US-Mexico border. She told The New York Times in an interview published Friday that her appointment was only meant to last for the first 100 days of the administration, which is April 30. "They continue to drive toward the architecture that the president has laid out: an immigration system that is humane, orderly and safe," Jacobson told the Times. "I leave optimistically. The policy direction is so clearly right for our country."
