“You can take the five worst presidents in all of American history, put them together, and they could not cause - and did not cause - the harm that Biden did to our country in just 16 months,” RIA Novosti quotes him as saying during a rally of his supporters in Nebraska.
The former American leader added that the blame for the situation around Ukraine also lies with the current US president.
Earlier, Trump said that the American administration is destroying the United States and leading the country to hell.
