Honestly, I don't know if this is plagiarized. Commencement speeches have a lot of cliche in them. But -- the similarities here are striking, particularly the last moment which is unique. And it's not like the administration is known for its intellectual curiosity. Nor is it known for its honesty. And this wouldn't be the first time they plagiarized a speech. For all we know, they brought in the writer of Melania Trump's RNC speech and had her spruce things up a bit.
The comparison comes at the 1:30 mark.
