WASHINGTON (AP) — A major Democratic fundraiser and former commerce secretary under President Barack Obama has endorsed Joe Biden for president.

The former vice president’s campaign announced the endorsement of billionaire businesswoman Penny Pritzker on Wednesday. Pritzker’s support could give Biden a considerable fundraising boost.

Pritzker is an heir to the Hyatt Hotel fortune and played an instrumental role in Obama’s rise, helping him raise money for his Senate campaign and his 2008 presidential primary campaign against Hillary Clinton. Pritzker served as Obama’s commerce secretary from 2013 until he left office.

Pritzker praises Biden’s years of Washington experience and joins a list of Obama administration officials who have endorsed Biden.
