Documentary filmmaker Michael Moore swooped into Flint, Mich., Saturday pleading for Gov. Rick Snyder’s arrest and dared President Obama to visit his hometown to face its water crisis.

“We need the president of the United States here,” said Moore, who stood by about 200 protesters staged outside city hall Saturday, according to the Detroit News.

Obama is scheduled to stop by the North American International Auto Show in Detroit on Wednesday, but it’s unclear if the President will make the 60 mile trek north of the Motor City to oversee an emergency declaration he approved for Flint’s water crisis.

He also demanded investigations by the Center for Disease Control and U.S. Army Corps of Engineers.

“Do not ignore this tragedy taking place every day,” wrote Moore, initially imploring Obama to act, but later reprimanding him in an update for not helping enough.

“This may be Gov. Snyder's Katrina, but it will become your Bush-Flying-Over-New Orleans Moment if you come to Michigan and then just fly away,” Moore wrote in an open letter.

The Federal Emergency Management Agency granted Snyder’s request to cover 75% of the state’s costs on items such as bottled water and filters.

The problem goes deeper than aid, Moore claims, whose film credits include “Bowling for Columbine” and “Fahrenheit 911.”

Snyder ignored the toxic perils of funneling drinking water from the Flint River, Moore alleged, accusing the two-term incumbent of choosing a cheap fix pending a new pipeline because of Flint's majority black population.

55% of the Flint's population is black, according to census data.

“My city has been pummeled by General Motors, Wall Street and the State and Federal governments,” Moore wrote. “It's no surprise that the Republicans who control our State Capitol in Michigan didn't have to worry about any push-back from the residents of Flint because, to them, that's just a bunch of eviscerated black people who have absolutely no power.”

Moore has been gunning for Snyder’s prosecution for at least two weeks, collecting about 118,000 signatures in a petition posted to his website alleging Snyder allowed a toxic amount of lead seep into the city’s drinking water.

He “knew that toxins, pollutants, and eventually lead was leaching into the water and being sent into the taps of people's homes," Moore said.

Moore also challenged Democratic presidential candidate Hillary Clinton to stop by Flint during her visit to Michigan on Tuesday.

He thanked Bernie Sanders for issuing a statement Saturday echoing Moore’s call for Snyder’s resignation, blaming the governor for poisoning the city’s population of about 100,000 people.

“There are no excuses,” Sanders wrote. “The governor long ago knew about the lead in Flint’s water. He did nothing. As a result, hundreds of children were poisoned. Thousands may have been exposed to potential brain damage from lead. Gov. Snyder should resign.”
