The National and Sleater-Kinney were in DC this weekend to protest Donald Trump’s inauguration, and both bands played at the Women’s March On Washington official after-party at the 9:30 Club last night. Proceeds from the event went to benefit Planned Parenthood, and during their set, Sleater-Kinney covered Creedence Clearwater Revival’s “Fortunate Son” with the National’s Matt Berninger, Dirty Projectors’ Dave Longstreth, and Planned Parenthood president Cecile Richards shouting along on backup vocals. Ted Leo, Tig Notaro, Samantha Ronson, and Janeane Garofalo also performed at the show. Watch below.

What an amazing way to cap off today's historic march. Played a benefit for @plannedparenthood with one of my favorite bands, @ntnl, as well as many other inspiring folks. Thank you @cecileonroad for asking us. Thank you to everyone who came out in support of PP. #sleaterkinney
