Barack Obama hit the campaign trail on Thursday in support of his old friend Kamala Harris, calling out Donald Trump in a blistering speech while wondering aloud if he has ever changed a tire—or a diaper.
The question even prompted one crowd member to shout “His own!”—eliciting a laugh from the former president.
At the Pittsburgh rally, Obama spent much of the time criticizing his successor. He said that while he understands why some voters are looking to “shake things up” given the current economy, “What I cannot understand is why anybody would think that Donald Trump will shake things up in a way that is good for you, Pennsylvania.”
