The letter rose to controversy earlier this week when Sen.

McConnell led a GOP vote to bar her from speaking.

“Sen. Warren was giving a lengthy speech,” McConnell explained. “She had appeared to violate the rule. She was warned. She was given an explanation. Nevertheless, she persisted.”

The phrase by McConnell has since been turned into a "feminist rallying cry."

According to reports, about 400 protesters gathered Friday night to read the letter by King. They shared their experience on social media sites, with the #LetterToMitch and #LetLizSpeak.
