The August 24 fundraiser, to be co-hosted by Apple vice president Lisa Jackson, will raise money for the Hillary Victory Fund, a committee backing the Clinton campaign, the Democratic National Committee, and 38 state Democratic parties, Buzzfeed reported on Friday citing an invitation to the event.

Apple (AAPL) declined to comment.

Cook has been bipartisan in his fundraising activities so far this year. Last month, he held a fundraiser for Republican House Speaker Paul Ryan. The June 28 breakfast in Menlo Park, Calif. was co-hosted by Apple treasurer Gary Wipfler. Apple does not have a political action committee.

Fellow tech company leader Brian Krzanich, CEO of Intel (INTC), raised a firestorm of protest last month when word leaked that he was holding a fundraiser for Republican presidential nominee Donald Trump. Krzanich quickly cancelled the event, explaining later at Fortune‘s Brainstorm Tech conference in Aspen this month that he had never intended to hold a fundraiser but “a conversation about issues.”

Due to discomfort with Trump, Apple declined to donate money or equipment to back the Republican convention in Cleveland, although it had provided such support in the past. Trump called for a boycott of Apple products earlier this year after the company declined to provide the FBI with security-weakened software to help crack an iPhone used by one of the San Bernardino shooters.

The tech industry, in general, has favored Clinton over Trump with its donations. Trump received a total of just $117,000 in donations from the entire tech sector, compared with almost $3.3 million given to the former Secretary of State, according to research by Crowdpac.

Trump’s comments about immigration and encryption, his call to boycott Apple products, along with his personal attacks on Amazon.com (AMZN) CEO Jeff Bezos have all been seen to hurt his standing with tech sector voters.
