There's been no bigger issue [VIDEO] facing the American people in recent years like what the future holds on the topic of health care. As the Republican Party attempts to get on the same page to repeal and replace the affordable care act (Obamacare), Donald Trump is speaking out after Sen. John McCain announced he would not support the GOP's most recent bill to do just that.

Trump on McCain

It all started back in January 2010 when former President Barack Obama signed the Affordable Care Act into law. During the remainder of his presidency, Obama faced massive backlash [VIDEO]from conservatives and the Republican Party who voted over 60 times in Congress to repeal Obamacare, despite the obvious threat of a veto by the commander in chief.

When the 2016 presidential election rolled around, repealing Obamacare became the one issue all Republicans could get behind, with Donald Trump making the most convincing argument which helped propel him to the party's nomination. Despite vowing to erase Obamacare from law as part of his campaign message, the former host of "The Apprentice" has struggled to do just that, as in-fighting within the GOP has become commonplace. Despite this, GOP senators Bill Cassidy and Lindsey Graham put forward their bill, which appeared to have enough support to pass through the Senate, until Arizona Sen. John McCain decided he would be voting "no." In response, Trump lashed out at the veteran senator during a string of tweets on September 23.

Taking to his Twitter account on Saturday morning, Donald Trump wasted no time ripping in to John McCain for refusing to support the Cassidy-Graham health care bill.

"John McCain never had any intention of voting for this Bill, which his Governor loves," Trump tweeted, before adding, "He campaigned on Repeal & Replace. Let Arizona down!"

"Chuck Schumer sold John McCain a bill of goods. Sad." Donald Trump tweeted out. As the president continued to send out tweets in support of the GOP bill, he also doubled down his attacks on John McCain while highlighting the senator's friendship with Lindsey Graham, tweeting, "McCain let his best friend L.G. down!"

Donald Trump didn't stop there, as he went on to tweet to Rand Paul in an attempt to patch things up with the senator who previously came out against the Republican alternative to Obamacare.

Trump's morning tweetstorm doesn't come as a surprise, as the president venting on social media has become commonplace for the commander in chief. In addition, Trump has a well-documented feud with John McCain dating back to the early day of the 2016 election cycle when the president mocked the senator for being captured as a POW during the Vietnam War. Despite McCain recently going public with having brain cancer, Trump shows no signs off holding back his criticism.

As has been the case over the last nine months, the Affordable Care Act is hanging in the balance, with its future being determined by a select few in the United States Senate. While John McCain's opposition makes it more difficult for Donald Trump and the GOP to strip the current law from the books, only time will tell if it gets done.
