Argentine President Javier Milei is facing a corruption probe into his promotion of a meme coin, which is a highly speculative form of cryptocurrency that’s seen a recent surge in popularity after President Donald Trump and his wife launched tokens of their own.

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.

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.”
