Health and Human Services Secretary Tom Price stressed that lawmakers are still early in the process, saying, "We'll work through" the disagreements over the plan because it is "an important process." That resistance and other hurdles threaten to slow the legislation and delay other parts of President Donald Trump's agenda that the administration plans to address following health care.
"This is the beginning of the process and we look forward to working with them and others," Price told reporters during the daily White House briefing.
Price stood next to a table which featured a printed copy of Monday's bill and the legislation by which the ACA was adopted during the Obama administration. After Price spoke, press secretary Sean Spicer repeatedly pointed out that the Democratic bill was much larger, arguing that it showed government's outsize influence on the health-care system.
The Republican plan replaces the individual mandate, which requires most Americans to have coverage or pay a tax penalty, with a 30 percent surcharge if customers go weeks without insurance. Tax credits will also replace the ACA subsidies.
Republican Sen. Rand Paul of Kentucky has called the GOP proposal "Obamacare Lite," while the conservative group Heritage Action for America said it "not only accepts the flawed progressive premises of Obamacare but expands upon them."
