The White House has committed an embarrassing blunder over an Oval Office carpet quotation, which they thought belonged to Martin Luther King but in fact, doesn't.

The original author is in fact a now-forgotten 19th century activist - Theodore Parker, a Boston preacher and campaigner against slavery, reports The Telegraph.

The new beige carpet contains the quote "The arc of the moral universe is long, but it bends toward justice," which Dr. Martin Luther King often used in his speeches for black rights which paved the way for the current White House occupant, to emerge as the first black leader of America.

However Dr King never claimed he had come up with it as his own.

Parker also first used the phrase "government of all the people, by all the people, for all the people" 13 years before President Abraham Lincoln, another great inspiration for US President Barack Obama.

It too is woven into the rug. (ANI)
