But not everyone was around to hear it.
Rogen took to Twitter on Wednesday to call out 16 members of the Senate Subcommittee on Labor, Health and Human Services, Education, and Related Agencies who didn't make it to his testimony. Only two, Sen. Jerry Moran, R-Kan., and Sen. Tom Harkin, D-Iowa, were there for his remarks.
"Not sure why only two senators were at the hearing. Very symbolic of how the Government views Alzheimer's. Seems to be a low priority," Rogen tweeted.
He also shared a photo of the empty seats:
All those empty seats are senators who are not prioritizing Alzheimer's. Unless more noise is made, it won't change. pic.twitter.com/xDW6tlMHmH— Seth Rogen (@Sethrogen) February 26, 2014
.@SenatorKirk pleasure meeting you. Why did you leave before my speech? Just curious.— Seth Rogen (@Sethrogen) February 26, 2014
Rogen founded the organization, Hilarity for Charity, with his wife Lauren Miller, to raise money for families struggling with the disease and for research.
"I came here today for a few reasons. One, I'm a huge House of Cards fan. Just marathoned the whole thing, had to be here," Rogen joked during his testimony, which you can watch in full below.
"Two, is to say, people need more help. I've personally seen the massive amount of financial strain this disease causes and if the American people ever decide to reject genitalia-driven comedy, I will no longer be able to afford it," he added. "I can't begin to imagine how people with more limited incomes are dealing with this."
