Senate Republicans are preparing to take a procedural vote Tuesday on their effort to repeal and replace ObamaCare.

Warren said in a video she shared along with her tweet that Republicans are going to "take us to the floor to vote on going forward on something that they're calling a healthcare bill."

"Now I say something, because nobody's read it. Nobody knows what it's in it. But they want to go to the floor and start so they will be able to pass a repeal of the Affordable Care Act," she said.

"This is the moment. We've got to make our voices heard louder than ever."

Warren called for people to speak out and tell their stories.

"This is not a drill. This is the real thing," she said in the video.

"The Republicans are moving forward, and it's up to the rest of us to fight back."
