It’s tough to say which of the 2020 wannabes is the biggest phony, but you can make a strong case for Liz Warren.

“I am sorry for harm I have caused,” Warren said Monday at a presidential candidates forum on Native American issues. She was referring to the fact that she spent much of her adult life falsely claiming she’s part American Indian in an attempt to advance her career.

Yet what action, exactly was she sorry for?

Was she apologizing for claiming to be Native American in the first place? That she spent years appropriating the identity of a minority group to advance her career?

It certainly helped her, despite her denials and those of the left-leaning media. Recall that Harvard got to brag about having a Native American on its staff after hiring her as a faculty member there.

Clearly, the school was grateful — and that was good for her.

Or was she apologizing for the DNA test that was supposed to confirm her Native American ancestry?

When the results showed she’s between 1/64th and 1/1024th Native American, she claimed it was proof.

Which was utter nonsense. But again, the media trumpeted the results as vindication.

Except Native Americans were only more furious after the test: The results prove nothing, they said. And anyway, being a Native American goes beyond one’s DNA.

And so, on Sunday, just before the Native American forum, her campaign scrubbed her website of mentions of her Indian heritage and the DNA results.

Now she says she’s “sorry.” For saying she was Native American? Or that she got caught?

Fact is, Warren isn’t really sorry for anything. She’s already proven that she’ll do or say anything to benefit herself.
