James Murdoch is the former chairman of 21st Century Fox and the son of media mogul Rupert Murdoch. Unlike his conservative father, James is a liberal; his wife, Kathryn Murdoch, is a major donor to center-left causes, both personally and through her Quadrivium Foundation.
In 2019, Murdoch donated $100 million to the Quadrivium Foundation, which he co-founded with Kathryn, in the form of shares in the Walt Disney Corporation.  This donation was made on the same day Disney bought 21st Century Fox and its assets such as 20th Century Studios.   Quadrivium then went on to give over $25 million in grants to left-of-center organizations like the Environmental Defense Fund, to whom Quadrivium gave $11 million in grants in the 2019 fiscal year.  According to a CNBC article, Quadrivium committed to giving over $43 million to “climate change related” groups.  In 2019, Quadrivium made over $38 million worth of donations to various election-related organizations, some of which were dedicated to opposing voting restrictions.
