But in dismantling large parts of the Affordable Care Act, the Senate bill would increase the number of people who are uninsured by 22 million, leaving 49 million uninsured by the year 2026.
Johnson is among four conservative senators, a group that includes Paul, who say the Senate bill doesn't go far enough in repealing the law known as Obamacare.
The CBO concluded that the Senate bill will result in 22 million Americans losing their health insurance over the next decade, including 18 million next year alone.
In response to the CBO's analysis, the White House on Monday released a statement meant to undermine its credibility: "The CBO has consistently proven it can not accurately predict how healthcare legislation will impact insurance coverage".
Already, an amendment has been added since the legislation was unveiled last week, a provision would lock people out of buying insurance for six months if they lacked coverage for more than about two months in the prior year.
"Obscene. Unconscionable. The nonpartisan Congressional Budget Office has just confirmed that Pennsylvania families will pay higher costs for less care with fewer protections under the Senate Republican health care scheme in order to lavish the wealthiest with tax cuts".
Johnson said he spoke with President Trump, who's been whipping reticent senators, for half an hour on Sunday, but vowed to his hometown paper that he's "not going to be bullied or pressured by anybody".
The bill rolling back much of President Barack Obama's 2010 health care law has been one of the party's top priorities for years, and the delay is a major embarrassment to Trump and McConnell.
"The Senate bill would cut annual household taxes by about $670 on average".
The chamber also lauded the health bill for preserving "the employer-sponsored health care system that 177 million Americans depend on for quality coverage".
The dismal CBO score could foil Senate Majority Leader Mitch McConnell's plan to rush the sweeping legislation to the floor before July 4.
Since the release of the bill's draft last week, five Republican senators have spoken out against the BCRA.
