Senate Majority Leader Mitch McConnell (R-Ky.) unwittingly gave women a new rallying cry when he silenced Sen. Elizabeth Warren (D-Mass.) on Tuesday night.

“She was warned. She was given an explanation,” he said. “Nevertheless, she persisted.”

#ShePersisted almost immediately began trending on Twitter. 

Warren had been attempting to read a letter written in 1986 by the late Coretta Scott King ― civil rights hero and widow of Martin Luther King Jr. ― that criticized Sen. Jeff Sessions (R-Ala.), then a U.S. attorney who had been nominated for a federal judgeship. 

McConnell invoked Rule XIX, which said: “No Senator in debate shall, directly or indirectly, by any form of words impute to another Senator or to other Senators any conduct or motive unworthy or unbecoming a Senator.” King’s letter argued that, during Sessions’ time as a prosecutor in Alabama, he “used the awesome power of his office to chill the free exercise of the vote by black citizens.”
