In less than 100 days, this new administration has caused so much harm and destruction, said Biden during his speech, which was held at a conference in Chicago.
The former president also placed great emphasis on criticizing his successor Donald Trump for having spent a significant part of the mandate period's first months cutting into the public sector, including the authority responsible for the country's social insurance system.
Biden withdrew last summer from the attempts to be re-elected after a very weak performance in a duel with Trump and instead handed over the task to Vice President Kamala Harris.
