美國總統川普（Donald J. Trump）於2017年4月29日晚間七點三十分（美東日光節約時間［EDT，Eastern Daylight Time］，換算為台灣時間4月30日上午七點三十分），在賓州哈里斯堡（Harrisburg, Pennsylvania）展演中心（Pennsylvania Farm Show Complex and Expo Center）舉辦群眾大會，發表長達五十八分鐘的上任百日演說。
他缺席白宮記者晚宴（White House Correspondents Dinner）前往賓州演說，藉由群眾大會造勢，藉此宣揚上任僅一百天，已實現一個個競選諾言。並且自誇上任之後迅速任命大法官，還讚許自己選擇退出跨太平洋夥伴協議（TPP，Trans-Pacific Partnership）是個明智的決定。他在演講中聲稱會保住賓州民眾的就業機會，並且為產業界爭取更多空間，促使汽車業回歸美國製造。並且強調他將實踐修築美墨邊境圍牆的競選承諾，以阻止非法移民偷渡美國。
接著，川普話鋒一轉，提到中國大陸，雖然他在競選時曾批評中國大陸操縱匯率，不過，自從川習會之後，川普稱讚習近平出面協助解決北韓問題，是個大好人。川普在這場演說中花費將近十二分鐘，批判散播「假新聞」（fake news）的媒體，點名CNN、MSNBC和《紐約時報》（New York Times），揶揄這些對他不利的媒體，導致他不想參加當天的白宮記者晚宴，而選擇到賓州哈里斯堡面對群眾演講。此外，他朗讀 The Snake（Oscar Brown, Jr. 寫於1963年），暗諷非法移民如同毒蛇狠心，關鍵時刻忘恩負義反咬救命恩人一口。
川普是在2017年1月20日中午12點（美東時間［EST，Eastern Standard Time］，台灣時間1月21日凌晨1點）宣誓就職美國第五十八屆（第四十五位）總統，到4月29日上任滿一百天。

Thank you. Ladies and gentlemen, it is truly great to be back in the wonderful, beautiful state of Pennsylvania. I love this state and I love the people of this state. It’s special and it carried us through a big, beautiful victory on November 8th.
I want to recognize some of our friends that have helped us so much. Congressman Scott Perry. G.T. Thompson. A couple of my originals, Mike Kelly — who I watched on television. He was great. Where's Mike Kelly? Where is Mike Kelly? He's here someplace. Where is he? Boy, were you great on television this morning. And, of course, one of our other originals, Congressman Tom Marino. Right? Thank you. Thank you, Mike. Thank you, Tom.
As you may know, there's another big gathering taking place tonight in Washington, D.C. Did you hear about it?
A large group of Hollywood actors and Washington media are consoling each other in a hotel ballroom in our nation's capital right now. They are gathered together for the White House Correspondents Dinner without the President. And I could not possibly be more thrilled than to be more than 100 miles away from Washington Swamp spending my evening with all of you, and with a much, much larger crowd and much better people.
And look at the media back there. They would actually rather be here, I have to tell you. Media outlets like CNN and MSNBC are fake news. Fake news. And they're sitting and they're wishing, in Washington — they're watching right now, they're watching. And they would love to be with us right here tonight. But they're trapped at the dinner, which will be very, very boring. But next year, maybe we’ll make it more exciting for them in Washington, and we’ll show up. But we have a good chance of showing up here again next year, too.
