After weeks of bad press and plummeting favorability ratings, Hillary Clinton seems to have turned a corner in the court of public opinion. With two new major endorsements and a string of minor victories (and with Donald Trump’s campaign once again imploding) the former secretary of state is looking more presidential by the day. In fact, she might even be cool again.

Clinton started the week off right when she literally made history by clinching the Democratic nomination ahead of Tuesday’s primaries. By passing the 2,383 delegate threshold, the former New York senator became the first woman in history to lead a presidential ticket for a major U.S. political party. Coming off her win over Vermont senator Bernie Sanders, Clinton funneled her momentum into a blistering attack against Trump. In an interview with the Associated Press on Wednesday, she labeled her presumptive opponent a “demagogue” and condemned him for his racially charged remarks about Judge Gonzalo Curiel.

Then came the endorsement from Barack Obama. On Thursday, her former rival gave his blessing to succeed him in the White House, proclaiming, “I’m with her.” On the heels of a meeting with Sanders, the president gave Clinton some pretty high praise—with a side of self-deprecation—when he said, “I don’t think there’s ever been someone so qualified to hold this office.” Self burn.

It was immediately after receiving Obama’s endorsement, however, that the “texts from Hillary” lady boss that Democrats fell for in 2012 suddenly returned to the spotlight with a well-timed tweet. When Trump took to Twitter and fired off a dismissive tweet (“Obama just endorsed Crooked Hillary. He wants four more years of Obama—but nobody else does!”), Clinton responded by retweeting Trump’s attempted insult with the simple message, “Delete your account.” The tweet instantly blew up and had garnered more than 426,000 retweets and over 526,000 likes by Friday afternoon.

Hillary’s big week culminated in an endorsement from Elizabeth Warren, the massively popular Massachusetts senator who was one of the last major holdouts to give Clinton their stamp of approval—and maybe offer herself as a potential running mate. As everyone’s favorite Trump attack dog and an outspoken critic of big banks, Warren’s approval marks a big step toward unifying the Democratic Party behind Clinton. She even sent her own sassy tweet at Trump, boosting Hillary’s original: “No, seriously — Delete your account.” Hey, if denim overalls can have a resurgence, why can't Clinton?
