WASHINGTON -- The nation's doctors, hospitals and health insurance plans are unified in their opposition to the latest Republican bill to dismantle former President Obama's Affordable Care Act.

In a joint statement on Saturday, major groups such as the American Medical Association, the American Hospital Association, America's Health Insurance Plans and the BlueCross BlueShield Association called on the Senate to reject the bill sponsored by GOP Sens. Lindsey Graham and Bill Cassidy.

The groups say, "Health care is too important to get wrong."

They warn that under the bill patients and consumers will lose important protections and those with significant illnesses will be charged higher premiums and may not be able to buy coverage.

They also say the cuts to Medicaid would cause millions of Americans to lose their coverage - and the changes would weaken individual insurance markets, making coverage more costly.

President Trump lashed out Saturday against Arizona Sen. John McCain, who said Friday that he couldn't support this bill. On Twitter, Mr. Trump wrote that "Democrats are laughingly saying that McCain had a "moment of courage."

Democrats are laughingly saying that McCain had a "moment of courage." Tell that to the people of Arizona who were deceived. 116% increase! — Donald J. Trump (@realDonaldTrump) September 23, 2017

Arizona had a 116% increase in ObamaCare premiums last year, with deductibles very high. Chuck Schumer sold John McCain a bill of goods. Sad — Donald J. Trump (@realDonaldTrump) September 23, 2017

John McCain never had any intention of voting for this Bill, which his Governor loves. He campaigned on Repeal & Replace. Let Arizona down! — Donald J. Trump (@realDonaldTrump) September 23, 2017

At a campaign rally Friday night for Alabama Sen. Luther Strange, Mr. Trump said it is going to be "a little tougher" to pass the bill without McCain.

"We might have to go back again, and again," the president said, comparing the health care fight to a wrestling match where only the strong continue to rise up and keep swinging.

"You can't quit when you have one or two votes short," he said.

Mr. Trump also criticized Kentucky Sen. Rand Paul, who said he will not vote for the bill, and Alaska Sen. Lisa Murkowski, who voted against the health care bill in July but has not given a definitive answer yet on this bill.

I know Rand Paul and I think he may find a way to get there for the good of the Party! — Donald J. Trump (@realDonaldTrump) September 23, 2017
