Im trying to find a proper word or phrase to describe this situation.
A person initially claimed that theres no pollution. Then later he or she turned around to say that there is some pollution due to faulty system. The latter statement detracts from the initial claims.
Wanted to know if theres a term, word or phrase that can be used to describe this.
Currently Im just using "turned around on his or her initial statement" but it sounds odd and wrong.
