The Trump Resistance is putting pressure on Senators to block the Republican healthcare bill—even as Senate Republicans announce that they’ll delay a vote as Sen. John McCain of Arizona recovers from surgery he had on Friday to remove a blood clot from above his eye.

Majority Leader Mitch McConnell (R-Ky.) previously had to delay the vote until after the July 4th recess as Republicans searched within their ranks for enough votes to pass the deeply unpopular bill. McConnell had been pushing for a vote on Tuesday.

In recent weeks, many Americans have been contacting their Republican senators to demand “no” votes on the legislation. The national organization Indivisible is calling for a Day of Action on Tuesday, urging Americans to protest at the offices of Republicans who are undecided on the bill. And on Monday the group UltraViolet is holding demonstrations outside the offices of senators Bill Cassidy (R-La.) and Rob Portman (R-Ohio), two so-called moderates who are considered potential “no” votes.

While Republicans attempt to sway senators to vote “yes” on Trumpcare, the Trump administration is hard at work spreading misinformation about the bill. At the National Governors Association on Friday, Vice President Mike Pence urged governors from across the nation to back the bill, telling them, “President Trump and I believe the Senate healthcare bill strengthens and secures Medicaid for the neediest in our society, and this bill puts this vital American program on a path to long-term sustainability.”

The non-partisan Congressional Budget Office (CBO) found that contrary to Pence’s pitch, an earlier version of the bill would have taken away healthcare for 22 million citizens over the next decade, including 15 million Medicaid recipients. A CBO score of the new version will be released Monday, and experts say the analysis will likely be similar.

“I don’t see a lot here that would meaningfully change the CBO score,” said Cynthia Cox of the non-partisan Kaiser Family Foundation, a think-tank focusing on health policy, in an interview on Friday with Business Insider. “We’re still likely to see many millions of people losing or going without coverage as a result of this bill. Although some of the taxes on wealthy people are retained, the bill doesn’t appear to use much of that to cover low-income people.”
