Porn titan Larry Flynt is offering a US$10 million prize for information leading to US President Donald Trump's impeachment and removal from office.
The Hustler publisher made the offer in a full-page advert taken out in The Washington Post on Sunday.
"The attempt to impeach Donald Trump will strike many as a sour-grapes plot by Democrats to overturn a legitimate election," the 74-year-old wrote, "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."
The ad lists a number of 'offences' Mr Flynt says should result in his impeachment, including firing FBI director James Comey, inciting racial hatred and telling "bald-faced lies".
"Impeachment would be a messy, contentious affair, but the alternative - three more years of destabilising dysfunction - is worse," he says.
"Both good Democrats and good Republicans who put country over party did it before with Watergate. To succeed, impeachment requires unimpeachable evidence. That's why I'm making this offer."

Mr Flynt says he doesn't expect Mr Trump's "billionaire cronies to rat him out", but hopes someone will.
"I could use that $10 million to buy luxuries or further my businesses, but what good would that do me in a world devastated by the most powerful moron in history?"
The White House is yet to comment on the offer.
Flynt has dabbled in politics as both a Democrat and a Republican, and endorsed Hillary Clinton last year.
In 2012 he offered a US$1 million bounty for information about Republican candidate Mitt Romney's tax returns, and made a similar offer in the 1990s for information about President Bill Clinton's extramarital affairs.
