Big lie

The big lie () is a lie of the truth, used as a propaganda technique. The German expression was created by Adolf Hitler, when he wrote his 1925 book "Mein Kampf", to describe the use of a lie so big that no one would believe it. 
In the 21st century, the term has been applied to attempts to overturn the result of the 2020 U.S. presidential election by Donald Trump and his supporters, specifically the false claim that the election was stolen.
