Larry Flynt, the founder and publisher of Hustler magazine is offering a $10 million  reward for information leading to the impeachment of President Donald Trump.

Fox Anchor Liz Claman, who broke the story, tweeted an image of an advert for the money. Flynt himself subsequently retweeted the story. Hustler had not replied to a request for comment at the time of publication.

The advert says: “Buried in Trump’s top-secret tax returns or in other records from his far-flung investments there may be a smoking gun.”

“The attempt to impeach Donald Trump will strike many as a sour grapes plot by Democrats to overturn a legitimate election,” it continues.

“But there is a strong case to be made that the last election was illegitimate in many ways—and that after nine tumultuous months in office, Trump has proven he’s dangerously unfit to exercise the extreme power accrued by our new ‘unitary executive.’”

The full-page advertisement says that Trump “only” won the election thanks to the “quirks” of the electoral college, which it calls “a real anachronism today.” It accused Republicans of a “scorched-earth spree of gerrymandering” after the 2010 census.

The advert says that Trump’s missteps include “inciting violent civil strife with his racial dog whistling,” “gross nepotism,” and “sabotaging” the Paris accord on climate change.

“Most worrisome is that, long before a climate change apocalypse strikes, Trump might trigger a nuclear world war,” it adds.

“Impeachment would be a messy, contentious affair,” the ad concedes, “but the alternative—three more years of destabilizing dysfunction—is worse.”

Flynt also offered a similar reward in 1998, during the impeachment trial of former President Bill Clinton. He has also shared clips from Hustler criticizing Trump, calling him a “buffoon” and a “narcissist,” and a piece calling on the Democrats to be “more than the party of no.”
