Obama campaign manager Jim Messina issued a fundraising appeal based on the hidden video comments, telling supporters:
If we don't come through for President Obama right now, this will be the guy making big decisions that affect us and our families every single day
An Obama adviser said the Democratic campaign might use Mr Romney's comments from the fundraising video in television advertisements.

Mitt Romney has confirmed a secretly filmed video of him describing Obama supporters as scroungers who pay no income tax is authentic.
