Joker Joe has been caught red-handed twice in his life for plagiarizing. Once in law school in a paper, I believe, and once as a candidate in a speech.
Looking at the side-by-side comparisons CNN presents, the information is similar but the sentence and paragraph constructions are different enough that a reasonable person wouldn't call it plagiarizing.
This is coming from CNN, not known for being truthful themselves nowadays. They have both a liberal agenda and propensity for creating and pushing fake news.
Geez, if they had vetted Obama and Biden like they are trying to do here, we wouldn't be in the mess we're in now.
My daughter had a college textbook that warned about plagiarism. It cited Biden as an example.
