Donald Trump weighed in Monday on the torching of a huge Staten Island lawn sign supporting his presidential bid — personally thanking the homeowner who put it up and commending the artist on his handiwork.

Sam Pirozzolo said the Republican candidate called his cellphone around 4 p.m., saying: “This is Donald Trump. I saw what happened all over the news. I appreciate everything you are doing.”

“It’s horrible what happened to you. I hope you and your family are safe,” Pirozzolo said Trump added.

Neighbors alerted Pirozzolo to the flames that destroyed the 12-by-8-foot, hand-painted “T” with a flag motif shortly after 1 a.m. Sunday.

Both the NYPD and FDNY are investigating the incident as arson.

Pirozzolo — who was wearing a T-shirt emblazoned with the same design — said Trump’s call came while he and conservative Staten Island artist Scott LoBaido were waiting to do a TV interview.

LoBaido said he told Trump that “tomorrow, at 3 p.m., we are putting up another sign, and it’s going to bigger — it’s going to be huge.”

“He got a chuckle from that,” LoBaido said.

LoBaido, who specializes in patriotic paintings featuring images of Old Glory, said Trump also “told me he knows of my work.”

“He basically called to say how proud he was of us and how much he loves Staten Island. He said, ‘You guys out there on Staten Island have my back,’” LoBaido said.
