Deep-pocketed donors in the energy, real estate and casino industries contributed to a legal defense fund to help President Trump pay his allies’ legal bills resulting from the feds’ investigation into Russian election meddling, a report said Monday.

The fund, known as the Patriot Legal Expense Fund Trust, was launched in February 2018 — but has only raised about $200,000, The Daily Beast reported, a tiny fraction of what the total bills could amount to.

Through the end of June, the top donor to the fund was Geoff Palmer, a Los Angeles real estate tycoon and one of the Trump campaign’s biggest financial backers, who coughed up $100,000, according to the website, which got its hands on the group’s financial records.

Next was Phil Ruffin, a casino fat cat and Trump supporter who gave $50,000, and Continental Resources, the oil and gas company founded and chaired by Harold Hamm, a Trump donor and board member of the pro-Trump group America First Policies, who gave $25,000.

The fund also reported income from ProActive Communications, which is run by the legal expense fund’s spokesman, Mark Serrano, and which donated $15,200.

The commander-in-chief set up the fund to pay legal expenses incurred by White House officials and allies who might face exposure in special counsel Robert Mueller’s probe into Russian meddling.

The Republican National Committee and the Trump campaign have already picked up the tabs for many of the legal expenses incurred by Team Trump.
