Cover up – When where we last guilty of it ?

Cover up, … cover up is to hide from others getting to know. This term was commonly used during the 1972 water gate scandal, when the US president Nixon covered up his staff’s wrong doings
A definition that says what it better would be this – An effort or strategy of concealment

But before fingers are pointed at US president Nixon, or lately even bill Clinton etc… it would be good to see where it is found in the scripture.
