Joe Biden on Saturday offered a counterpoint to the dark and defiant Fourth of July message President Trump delivered at Mount Rushmore, striking notes of unity in a video and op-ed released on the nation’s 244th birthday.

The presumptive Democratic presidential nominee noted that the Founding Fathers were flawed, pointing out that President Thomas Jefferson owned slaves and that women were not granted the full rights of citizenship until 1920. But he said their ideas still offer hope.
