Larry Flynt, the founder of Hustler Magazine, bought a full-page ad in The Washington Post on Sunday, offering $10 million to anyone with information that could lead to President Donald Trump's impeachment.

The ad said there was a strong reason to believe the 2016 election was "illegitimate in many ways" because Trump lost the popular vote, and was voted in because of an Electoral College "quirk" and Republican gerrymandering.

"Trump has proven he's dangerously unfit to exercise the extreme power accrued by our 'unitary executive'," the ad read.

Best known for founding the sexually graphic Hustler Magazine, Flynt has used his fame to influence politics before, according to The Washington Post. He endorsed Democratic presidential candidate Hillary Clinton in 2016, and took out similar ads offering monetary rewards worth millions of dollars for information on Mitt Romney's tax returns, and for evidence that members of Congress or government officials had illicit sexual encounters.

Apparently one of the ads led to the resignation of Republican Congressman Bob Livingston in 1998 after he admitted he had extramarital affairs, according to CNN.

Flynt's ad went on to say there were several reasons Trump warrants impeachment, including his decision to fire former FBI director James Comey, his controversial response and "racial dog-whistling" following the white nationalist riots in Charlottesville, the risk that he might launch a nuclear war with North Korea, and his decision to pull the US out of the landmark Paris climate deal.

Comey's firing is currently the basis of an obstruction-of-justice case that special counsel Robert Mueller is investigating as part of his probe into Russia's interference in the 2016 election. Mueller also looking into whether the Trump campaign colluded with Moscow to tilt the election in Trump's favor.

Trump has also in recent weeks significantly ramped up his rhetoric against North Korea, which in turn has increased its nuclear aggression against the US.

The ad conceded that while impeachment would be a "messy, contentious affair," the alternative — another three years of a Trump presidency — was worse. Flynt also called for the release of Trump's tax returns, as well as other financial and business records, arguing that "there may be a smoking gun" and that "impeachment requires unimpeachable evidence."

The ad ended with Flynt saying that while he did not expect Trump's wealthy allies to turn on him, he believed that "there are many people in the know for whom $10 million is a lot of money."

Flynt said he could easily spend the $10 million on other things, "but what good would that do me in a world devastated by the most powerful moron in history?"
