Philanthropy
James joined the board of trustees of the Metropolitan Museum in 2010, and became the chairman of the museum's finance committee in 2014. In 2020, as the museum struggled with a revenue loss of 150 million dollars due to the COVID-19 pandemic, James was named co-chair of the board of trustees, sharing the leadership with attorney Candace Beinecke, beginning in January 2021. This was the first time the museum has had two chairpersons.
