JPMorgan CEO Jamie Dimon has refused to publicly take sides in the US election but his wife is campaigning for Harris.

Intellidex learned that Judy Dimon, the wife of JPMorgan Chase (JPM.US) CEO Jamie Dimon, a prominent political donor, campaigned for Kamala Harris in Michigan over the weekend. As the CEO of the largest bank in the United States, Jamie Dimon has refused to publicly endorse candidates from either party and has pledged to work with whoever is elected.

Earlier this year, Donald Trump promoted Dimon's support on his social media page, but the bank quickly denied it. Media reports earlier this year had already revealed Judy Dimon's work as a volunteer for the campaign. Last month, media reports said Dimon privately supported Harris and would consider a role in her administration.

According to reports, the longtime Democratic donor Judy Dimon's support has been more public, with her donating $250,000 to Harris and the Democratic National Committee. In a statement provided by the Harris campaign, she said: "This election is critical for our country, our core principles, our security and our economy. The freedoms, rights and opportunities that have benefited so many of us should be more, not less, for our children and grandchildren."

Last month, Harris dodged a question from reporters about whether she wanted Jamie Dimon in her administration, telling them she hadn't thought about her cabinet picks. When asked by reporters in Houston if she had spoken to Dimon about a role, Harris said: "We have 11 days. We haven't put together our cabinet yet."
