DHS Sec Alejandro Mayorkas' chief of staff resigns amid border crisis

A top official at the Department of Homeland Security (DHS) announced on Monday that she would be leaving the department at the end of this month, according to a report.
Karen Olick, chief of staff to Homeland Security Secretary Alejandro Mayorkas, "has decided to resign her position and pursue new opportunities," Mayorkas told DHS officials in an email obtained by Politico.
"We are grateful to Karen for her service during the critical first nine months of the new Administration," he added.

Olick’s role will be filled on a temporary basis by Jennifer Higgins, associate director of refugee, asylum, and international operations at U.S.
Citizenship and Immigration Services (USCIS), until a new replacement can be found, Politico reported.
Olick, a former chief of staff to longtime Sen. Barbara Boxer (D-Calif.), spent more than a decade as a managing director at Democratic consulting firm SKDK before going to DHS.

In July, U.S. Customs and Border Protection (CBP) reported that it had stopped 212,672 attempted crossings — the most in a single month since March 2000.
In addition to the border crisis, the department has also been tasked with resettling thousands of Afghans in the US after they were evacuated from that war-torn country in recent weeks.

"And I would ask all Americans to welcome them into our communities."
