So they wrote a letter :
Dear President Obama:
We are writing as the employees of American Energy Century Mine in Beallsville, Ohio. You have approved in a running television campaign ads about the Mitt Romney event that was held at our Century coal mine. These ads state that we were forced to attend this rally and that is blatantly false. There are numerous false statements and absolute lies concerning our participation in this event, we, the employees, mostly started by a local shock jock host. Since your approval is attached to these ads, you may not wish to support these mistruths. Why would you lie about the 500 working miners who have signed this letter? We, the employees of Century Mine, would request you immediately stop these false ads. Thank you. Century Mine employees.
This was the advert
And here is the Miners response ad
And the Miners full statement
If the President cannot be trusted to tell the truth in an advert what hope is there if he is re-elected to the WhiteHouse?
