Facebook’s cryptocurrency project Libra has been criticized by French and US officials. The authorities did not appreciate the innovative development of the social network and want to nip it in the bud. French Finance Minister Bruno Le Maire appealed to the heads of the Central Banks of the countries of the G7 to study Libra tokens. He believes that they can not be released. Member of the US Republican Party, Patrick McHenry, wrote a letter to the chairman of the US House Committee on Financial Services, Maxine Waters, demanding a hearing on the issue of the Libra virtual currency. Waters supported the McHenry initiative and proposed to impose a moratorium on the further development of the Facebook project.
