Argentina President Javier Milei is facing withering criticism, including some calls for impeachment, after promoting a new cryptocurrency on his social media account.

An Argentine judge was assigned on Monday to investigate President Javier Milei's role in promoting a cryptocurrency that crashed, the latest shockwave from a scandal that has threatened to slow the libertarian leader's momentum.

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.”
