WASHINGTON — Long Island’s Republican megadonor Robert Mercer and his daughter Rebekah had shifted their allegiance to Donald Trump a month before they rebuked their former favorite presidential candidate Ted Cruz on Saturday, federal records show.

Mercer, co-CEO of the hedge fund Renaissance Technologies of East Setauket, invested $13.5 million in a super PAC to back the Texas senator’s presidential ambitions, which ended when Cruz quit the race in May.

But a month ago, Mercer, his wife and daughter each contributed the maximum $5,400 to Trump’s presidential campaign fund. Robert and Diane each donated $5,400 and Rebekah gave $449,400 to Trump Victory, a joint fundraising committee with the Republican National Committee, filings with the Federal Election Commission show.

Over the weekend, Mercer, of Head of the Harbor, joined his daughter in a rare statement expressing disappointment and regret that Cruz refused to endorse Trump at the Republican National Convention.

A spokeswoman for the PAC did not respond to a Newsday query Friday. But on Saturday, Mercer and his daughter issued a statement to The New York Times.

Noting Cruz had pledged to support the GOP candidate, the Mercers said, “We are profoundly disappointed that on Wednesday night he chose to disregard this pledge.”

They added, “The Democratic Party will soon choose as their nominee a candidate who would repeal both the First and Second Amendments of the Bill of Rights, a nominee who would remake the Supreme Court in her own image. We need ‘all hands on deck’ to ensure that Mr. Trump prevails. Unfortunately, Senator Cruz has chosen to remain in his bunk below, a decision both regrettable and revealing.”

Meanwhile, Mercer’s super PAC — renamed from Keep the Promise I when it backed Cruz to Make America Number 1 to oppose Democrat Hillary Clinton — has remained idle since June 23, according to its July FEC filing. The PAC has $1.1 million in cash on hand.
