The closed-door event will be at the South Lake Trail home of Darlene Jordan, a former Massachusetts assistant attorney general, and husband Gerald Jordan, a hedge-fund financier and president of Boston-based Hellman, Jordan Management Co.
Gov. Rick Scott earlier this year named Darlene Jordan to the State University System Board of Governors.
The Jordans were major fund-raisers for Mitt Romney’s 2012 presidential campaign, contributing almost $600,000, according to the Center for Responsive Politics. Darlene Jordan was named in August to Donald Trump’s team of economic advisers.
The former president, like his brother, former Florida Gov. Jeb Bush, has refused to endorse Trump, while many officials from his administration have come out against the Republican nominee.
George W. Bush, however, has maintained a fairly robust schedule of fund-raising for Republican Senate candidates, in an election year where GOP control of that chamber is clearly at risk.

Rubio is in a tight race with U.S. Rep. Patrick Murphy, D-Jupiter. But Republican fund-raising committees have vastly out-spent Murphy and his Democratic allies.
