Liberal documentary filmmaker Michael Moore threatened to begin fracking off the Florida coast near President Trump's Mar-a-Lago resort.

His tweet appeared to be a response to a new administration proposal to increase offshore drilling for natural gas.

"Our fracking off the coast of Mar-a-Lago begins right after Labor Day," Moore said in a tweet referencing his upcoming TNT documentary series "Live From the Apocalypse." "I've already got the rig - a beautiful Halliburton G-0008 fracking system with a monster Caterpillar engine!"

"Here's our fracker! We'll be drilling right off the coast of Mar-a-Lago," Moore continued. "God Bless You Donald Trump for making this possible! The oil we drill just off your beach will pay 4 our entire show!"

Moore, a relentless Trump critic and liberal activist, targeted the president's luxury Palm Beach resort, a favorite vacation spot for the president. Florida is on a list of states that could see new drilling off their coastlines under a new proposal by Interior Secretary Ryan Zinke.

The plan would open up drilling rights sales for companies on much of North America's continental shelf in coastal areas near Alaska, California and Florida, which would be a boon to the fossil fuel industry.

Moore's tweets also come after the Trump administration rolled back offshore drilling safety regulations that were created after the Deepwater Horizon spill in 2010 killed 11 people and sent at least 4.9 million barrels of oil spilling into the Gulf of Mexico.

Environmentalists have warned that the expansion and deregulation of offshore drilling could be dangerous.

Trump has promised to unlock the nation's "great energy wealth" by promoting domestic oil and gas drilling to remain independent of foreign energy.
