As tension in American politics reaches an all-time high, feuds are popping up out of nowhere. The latest war of words comes from former half-term Alaska Gov. Sarah Palin who has set her sight on Massachusetts Sen. Elizabeth Warren over a phrase used by the popular liberal in recent weeks.

Palin on Warren

When Donald Trump first announced that he was going to run for president, his candidacy was initially viewed as a joke, with many predicting that he would quickly fade away before the race became too serious. As time moved on, Trump gained momentum as he went after each of his Republican primary opponents, embarrassing them during the debates and on the campaign trail.

Trump rode his new-found political popularity to the party's nomination last July, and eventually his upset general election win over Hillary Clinton. In that time, the former host of "The Apprentice" received backlash and support, as Americans were often split in how they viewed him. On of Trump's biggest critics has been Elizabeth Warren, whose name was heavily rumored to run for president during the 2016 presidential election, but ended up stepping aside to support Clinton. In contrast, Sarah Palin was one of the first high-profiled Republicans to publicly endorse Trump for president, which led to speculation that she could find herself in the White House in some capacity, and was even on the reported short list to become the vice president.

As reported by Mediaite on April 19, Palin is now continuing her feud with Warren, this time targeting the senator from Massachusetts for allegedly lifting a line she uses during her speeches.

On Tuesday, Elizabeth Warren took to her Twitter account and posted an image of herself with the "Fearless Girl" statue located in New York City, while adding the phrase "Fight Like A Girl" to her post.

In response, Sarah Palin was not pleased. As first reported in the right-wing Breitbart News on Wednesday, Palin is accusing Warren of plagiarizing the term "fight like a girl," claiming she was the one to use it in the political realm first.

Palin's problem

"Coming from liberals who urge women to claim victimization, 'Fight like a girl' just doesn’t sound the same," Sarah Palin noted before saying that people like herself are "legit fighters for equality" who use the term and also "mean it, live it, and will never give it up." Palin was also upset that Elizabeth Warren continued to use the term to promote her latest book during an interview with NPR Radio. As of press time, Warren has not responded to the comments made by the former 2008 vice presidential nominee.
