San Diego's Irwin and Joan Jacobs were among the high-profile guests invited to Thursday's White House dinner for Canadian Prime Minister Justin Trudeau.
The co-founder of Qualcomm & Chair of the Board of Trustees, Salk Institute and his wife were photographed as they arrived for the formal dinner.
The tech executive has been known to contribute millions of dollars to Democratic presidential candidates.
The Jacobs hosted President Barack Obama at their La Jolla home for a fundraiser in May 2014.
They invited approximately 250 people to their home in October to raise funds for Democratic presidential candidate Hillary Clinton.
