Many fed-up 9/11 families are hopeful as President Trump explores a federal takeover of the embattled museum and memorial at Ground Zero.

“I am delighted,” said Sally Regenhard, who lost her firefighter son Christian Regenhard, in the Sept. 11, 2001, terror attacks on the Twin Towers. “This is answered prayers.”

“It’s a godsend that the Trump administration – that Donald Trump – has heard the cries of the families,” continued Regenhard, who leads a group advocating for families of 9/11 firefighters.

A White House spokesperson told The Post preliminary exploratory discussions of a takeover are ongoing.

Trump pledged to make the site a federally-protected national monument on the campaign trail last year.

“I am announcing tonight that as president, I will officially make the Ground Zero site at the World Trade Center a national monument protected and maintained by the United States government,” Trump said at a Long Island rally in September.

He said the move would ensure the “hallowed ground and the memory of those who perished there will be preserved for all time – preserved forever.”

The proposal is gaining steam after The Post’s front page expose last month revealed skyrocketing salaries for execs of the nonprofit that runs the museum, even as its finances have been in the red for years.

Many frustrated 9/11 families have long pushed for the National Park Service to take control of the complex.

One of the families’ central demands has been to move the remains of 1,100 unidentified victims from the museum’s basement, and to include names of those who have since been identified by the city’s Office of the Chief Medical Examiner.

“In the future, especially the parents of the victims, they’re not going to be here to tell the stories,” said Regenhard, as she started crying. “No one will know that my son was a firefighter and that he perished in the death trap of Ground Zero.”

Elizabeth Hillman, President and CEO of the 9/11 Memorial & Museum, has rebuffed the idea of a federal takeover.

“At a time when the federal government is working to cut costs, assuming the full operating expenses for the site makes no sense,” she told The Post.

“We’re proud that our exhibitions tell stories of bravery and patriotism and are confident that our current operating model has served the public honorably and effectively.”

Trump is not expected at next week’s Ground Zero anniversary ceremony and is scheduled to attend a ceremony at the Pentagon. He’s due to be in the Big Apple later in the day to watch the Yankees take on the Detroit Tigers in the Bronx.
