A top Apple lobbyist is reportedly leaving the company after joining Joe Biden’s presidential campaign.

Cynthia Hogan, Apple’s vice president for public policy and government affairs, plans to leave her post next month, the iPhone maker told Axios and Bloomberg News.

Biden, the presumptive Democratic nominee, tapped Hogan and three others in late April to lead a committee that will vet candidates to be his running mate.

Hogan previously served as Biden’s chief counsel when he was a senator and Barack Obama’s vice president. She spent about two years as the NFL’s executive vice president for public policy before joining Apple in 2016.

Hogan will join former Sen. Chris Dodd, Rep. Lisa Blunt Rochester and Los Angeles Mayor Eric Garcetti on Biden’s vice presidential vetting panel. Biden has said he plans to pick a woman to join his ticket against President Trump.

Apple did not immediately respond to a request for comment Friday morning.
