Since Aug. 2014,just the tip sex teasing videos Donald Trump has referred to Sen. Elizabeth Warren as "Pocahontas" at least 26 times.

He mostly slings the slur on Twitter, but he's also repeated it during rallies, interviews, and at meetings with fellow government officials — all attempts to discredit the senator by painting her with an offensive nickname that propagates one of Trump's pet conspiracy theories.

His most recent use of the term was particularly tone deaf: he slid a non sequitur reference to "Pocahontas" in while speaking with Navajo code talkers at the White House on Tuesday -- people the president was supposed to be honoring, but ended up deriding.

"We have a representative in Congress who they say was here a long time ago. They call her 'Pocahontas,'" said Trump, apropos of nothing, except perhaps the fact that Warren has been lambasting him in the press for his support of the GOP tax bills.

The Navajo Nation has since characterized the remark as "culturally insensitive." Invoking a diverse community by dropping the name of a single individual -- let alone a tragic individual, whose story has been erased by mainstream media via the Disney film -- is a way of "othering." It reduces the complexities of a people to a single white-washed narrative.

Dr. John Norwood, general secretary of the Alliance of Colonial Era Tribes, explained why the term was problematic to ThinkProgress:

“The general use of the name is not — Pocahontas was a historic figure, so just simply using the name is not a racial slur,” Norwood, who is a member of the Nanticoke Lenni-Lenape Tribal Nation, said. “However, the use of it in a derogatory fashion to insult someone degrades the name and all it represents, and then it becomes a racial slur. The president was attacking a claim by Senator Warren about American Indian ancestry, and to insult that claim by calling her ‘Pocahontas’ turns the name into a racial slur.”

Meanwhile, Elizabeth Warren remains the only adult in the room, consistently sticking to the issues she champions while slamming Trump as unfit to govern. In May 2016, Warren criticized Trump for seeking to benefit from the 2008 housing meltdown -- and Trump's response was to trot out the "Pocahontas" line. She hasn't let Trump's name-calling stop her from talking about the minimum wage, student loans, and more.

In Warren's latest response to Trump's use of the line, she told MSNBC"it is deeply unfortunate that the president of the United States cannot even make it through a ceremony honoring these heroes without having to throw out a racial slur."

"Donald Trump does this over and over thinking somehow he's gonna shut me up with it," Warren said. "It hadn't worked in the past, it's not gonna work in the future."

Trump's "Pocahontas" insult stems from a 2012 brouhaha in which Warren was accused by a political opponent of using claims of Native American ancestry to promote her career. Naturally, the story is more complicated than that, which the New York Timesinvestigated in full. But overall, the Timesfound no proof that Warren ever received an advantage based on her claims to Native American heritage -- which is the weird, anti-affirmative action narrative that Trump peddles as fact.

But that hasn't stopped Trump and aides like Sarah Huckabee Sanders -- who had to defend Trump's remarks during the Navajo visit -- from repeating the conspiracy theory.

A "nickname" might sound harmless. But as we saw with "Crooked Hillary," Trump's epithetical bullying helps cement lies as truth, painting complicated situations and individuals with one wide, ugly stroke. When one reduces a story to a single word, it can never tell the whole truth. Or, as Elizabeth Warren has put it:

Here are all the times Trump has used the story of Pocahontas -- a Native American teenager, taken from her home in the Americas by a grown man, only to die across the ocean from her family -- in order to insult a political rival.

"Pocahontas Warren" first emerged in a retweet in 2014, seemingly coined by @TheAme19 whose Twitter bio now reads "Stand for the Flag; Kneel before the Cross," among other things.
