According to Politico, the shake up mostly revolves around the restructuring of her senior staff. Rohini Kosoglu, Harris's chief of staff in the Senate, and senior adviser Laphonza Butler have both been elevated to senior management positions.

Kosoglu and Butler will reportedly co-manage the campaign's departments in an effort to make the decision making process run more efficiently.

Juan Rodriguez will continue to serve as Harris's campaign manager, although some of his responsibilities will now be delegated to Kosoglu and Butler.

Rodriguez, in a statement to Politico, suggested that the moves were not spontaneous.

“We continue to grow our organization as we enter the fourth quarter, and it has always been the plan to bring on additional management to oversee an expanded staff," Rodriguez said.

"As we double our organizers in Iowa and South Carolina and expand our digital team, we're in a strong position to execute our plan and win the nomination," he continued.
