Chelsea Handler announced via Twitter she has donated $1 million to efforts to help Puerto Rico in the wake of Hurricanes Irma and Maria.

"I just gave 1,000,000 dollars to Unidos Por Puerto Rico. Where r ur donations, Koch Bros. Mercers, @realDonaldTrump? Day 1 of activism," Handler tweeted Thursday.

Handler said Wednesday she won't return for a third season of her Netflix docu-series "Chelsea" because she wants to focus on activism.

"My goal is to be better informed, raise my voice, and participate in a more meaningful way. I want to travel the country and visit areas and people I don't know enough about, speak at colleges and listen to students, and gain a better understanding of our political divide," Handler said earlier this week.
