"The Democratic caucus will not participate in the Republicans' sham process. No amendment will get a vote until we see the final legislation and know what bill we are amending,” Josh Miller-Lewis said in a text to Vox's Jeff Stein.

Daines introduced an amendment Wednesday night that would establish a government-funded healthcare system.

To be sure, Daines does not support single-payer healthcare. Rather, the amendment was a political maneuver to reveal internal strife among Democrats, who are divided in their support for such a system.

Sanders, a self-described democratic socialist who caucuses with the Democrats, has been among Congress's most vocal and fervent supporters of "Medicare for all."
