In an interview with CBS Bill Clinton made a slip-up that CBS tried to cover up by editing it out
An interview with CBS went terribly wrong as Bill Clinton attempted to cover up for Hillary Clinton's medical "faint" on 9/11. He blamed it purely on dehydration and said everything was going to be fine. However that's not all he said, but that's about all you'll here from CBS.
In an interview, Bill Clinton was asked if this was about a more serious health problem, to which he responded:
"Frequently, well not frequently, rarely but on more than one occasion the same sort of thing has happened to her". But when CBS broadcasted this interview they completely cut out the boldened part of the sentence in an attempt to make it look as though it was less serious.
This has been a point of controversy as many in the media point out CBS on their mistake. In the CBS News Article there is also no mention of the words said by Bill Clinton in that regard.
With that quote above in mind, we provide video of the interview released by CBS:
As you can see, definitely a point of controversy as many speculate that their doing so was in an attempt to make Hillary Clinton look better and help better defend Bill in his interview.
