Senate Democrats on Monday started their night-long protest over Republican plans to dismantle Obamacare by imploring people to reach out to Senate leadership.

“The way we are going to win this fight is if millions of people become engaged,” said Sen. Bernie Sanders, I-Vt., on Facebook Live. “The Republican plan defies very strongly what the American people want. The American people have said yes, we want changes in the Affordable Care Act. But you are not going to throw 20 million people off health insurance.”
