Sigh. Repeating a claim over and over does not make it true. Obama did not waive the work requirement for welfare.
Edited to add: And then there is the new anti-Obama movie, 2016: Obama's America. It grossed $6.2 million last weekend. This is maybe more a "let's take very thin evidence and create sandcastles with it" rather than out and out lies, but it is still frustrating. A lot of people will see that movie, but few of them will see Boston.com's fact check of it.
