Argentine President Javier Milei is facing calls for impeachment after promoting a little-known cryptocurrency, whose price soared then collapsed after his endorsement, leading to losses for thousands of investors.

Here’s what happened: Late Friday night, Milei fired off a tweet lending his support to a cryptocurrency token called $LIBRA. Milei described the coin to his nearly four million followers as a “private project dedicated to encouraging the growth of the Argentine economy,” claiming that it would be “funding small Argentine businesses and ventures.”

Argentinian President Javier Milei mocked opposition efforts to impeach him amid accusations of fraud after a cryptocurrency he shared on social media crashed, inflicting big losses on those who bought in.
