During her speech to the Republican National Convention last night, Melania Trump plagiarized sections of Michelle Obama’s 2008 speech to the Democratic National Convention nearly word for word. This is not a close call. This is not subject to debate. It happened.

When asked by reporters about this obvious instance of plagiarism, the Trump campaign has repeatedly denied that the speech contained plagiarism, with campaign chairman Paul Manafort saying “no cribbing” occurred and suggesting that it happened is “crazy.” This is obviously untrue. Since the Trump campaign officials have to realize this is obviously false, they are lying.

The Trump campaign, which has made untruths a cornerstone of its communications effort, is daring reporters to call its surrogates out for lying. And some are answering the challenge, like CNN’s Chris Cuomo. There’s little doubt that the campaign’s next move will be attacking the press for pointing out the plagiarism while continuing to deny that it happened.

Reporters have a choice: They can report that the paragraphs sure seem similar but the Trump campaign denies plagiarism, or they can acknowledge outright that the Trump campaign is lying.
