Filmmaker Michael Moore threatened Saturday to begin fracking off President Donald Trump's Mar-a-Lago resort in Florida to protest the administration's decision to open nearly all U.S. offshore waters to drilling for oil and natural gas.

Moore, who has long opposed Trump and his policies, took to Twitter:

We are back on the air in September — in prime time! “Michael Moore LIVE FROM THE APOCALYPSE!” Our fracking off the coast of Mar-a-Lago begins right after Labor Day. I’ve already got the rig — a beautiful Halliburton G-0008 fracking system with a monster Caterpillar engine! https://t.co/riUn0QgvkG — Michael Moore (@MMFlint) January 6, 2018

Here’s our fracker! We’ll be drilling right off the coast of Mar-a-Lago. God Bless You Donald Trump for making this possible! The oil we drill just off your beach will pay 4 our entire show! And any spills - we’re going to let the ppl of Florida keep whatever they collect 4 free! pic.twitter.com/iGq2f1Gi33 — Michael Moore (@MMFlint) January 6, 2018

Interior Secretary Ryan Zinke announced a plan Thursday to open nearly all U.S. offshore waters to oil and gas drilling, reversing protections in the Arctic, Atlantic and Pacific.

He said the draft National Outer Continental Shelf Oil and Gas Leasing Program for 2019 to 2024 would make over 90 percent of the outer continental shelf's total acreage available for leasing, including areas put off-limits by the Obama White House.

Florida Republican Gov. Rick Scott immediately opposed Zinke's plan, saying that he had asked to meet with the secretary to discuss "the crucial need to remove Florida from consideration."
