In a 2010 email that surfaced in late 2020, Joe Biden was critical of then-President Barack Obama’s decision to call out him for plagiarism. According to the New York Post, Biden wrote in the email that Obama showed “no grace” in bringing up the issue. The email was a response to advice from his son Hunter Biden, that included the phrase, “Plagiarism is the sincerest form of flattery!” Biden replied that Obama “had no class.” He did not elaborate on his comments.
