Larry Flynt, the pornography publisher, is offering "up to $10 million" to anyone who produces information that leads to President Donald Trump's impeachment and removal from office.

Laying out the offer in a full-page ad in the Sunday edition of The Washington Post, 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.’”

Listing a number of reasons for his removal, from “inciting violent civil strife with his racial dog whistling” to “sabotaging” the Paris accord on climate change, the ad states: “Most worrisome is that, long before a climate change apocalypse strikes, Trump might trigger a nuclear world war.”
