Seth Rogen to Congress: It’s Not About Pot

Seth Rogen used his trademark humor to deliver personal testimony on Alzheimer’s disease Wednesday before a Senate hearing on Alzheimer’s research. The “Knocked-Up” star said he came to the Senate for a few reasons -- the first being that he is a huge “House of Cards” fan, but more importantly, to request help for those dealing with the devastating effects of the disease.

Rogen asked a Senate subcommittee to increase funding for Alzheimer’s research. His mother-in-law suffers from early-onset Alzheimer’s.
