Donald Trump had still failed to pay tribute to the late John McCain's personal achievements after returning from a spot of golf on Sunday evening, adding insult to injury by additionally making no mention of the Florida mass shooting that had taken place that day.

The President of the United States instead chose to brag about his economic success in a tweet that highlighted lines from an article in the Washington Times.

'Mainstream Media tries to rewrite history to credit Obama for Trump accomplishments,' the tweet reads about former President Barack Obama. 'Since President Trump took office, the economy is booming. The stronger the economy gets, the more desperate his critics are. O had weakest recovery since Great Depression.'

It led to angry reactions from followers quick to point out he had not acknowledged the video game massacre in Jacksonville that had so far taken the lives of four people and injured 11.

In addition, the world was still waiting for Trump, 72, to send out a message that focused on Senator John McCain's incredible lifetime achievements following his passing away of cancer on Saturday.

Many notable names in politics, including Obama and Britain's Prime Minister Teresa May, had publicly honored the senator on a personal level.

'Why are you tweeting about what Obama did rather than saying anything even remotely useful or presidential about the terrible mass-shooting that took place hours ago in??,' one message read. 'Oh that’s right, cuz it doesn’t help your agenda in any way. YOU. ARE. SCUM.'

Bill Palmer, who states on his Twitter account that he has been blocked by Trump but followed by Obama, said: 'Three hours after the Jacksonville shooting, and you’re bragging about your own supposed accomplishments without even mentioning Jacksonville? No wonder everyone hates you! John McCain’s final "screw you" to Donald Trump.'

Ivanka Trump tweeted that afternoon about the Jacksonville, Florida mass shooting but followers were not impressed

Another user speculated that the leader of the free world may not be addressing the tragedy because it didn't fit in with his political agenda that's known for being harsh on immigration.

'Trump would prefer he were a few shades darker so he can use it as propaganda. It does little for his narrative for these shooters to be white,' Bridget wrote.

His daughter Ivanka Trump, who is his adviser on job creation, economic empowerment, workforce development and entrepreneurship, did mention the Jacksonville tragedy though.

'As we await further details, our hearts are with Jacksonville and all those affected by today’s tragic mass shooting,' she posted on the micro-blogging site.

Some Twitter users suggested Trump did not draw attention to the shooting because there was so far no link to suit his political agenda

POTUS was spotted arriving at the golf course on Sunday morning, less than 17 hours after the death of McCain.

The president has remained somewhat quiet about the Arizona Republican senator's death, drawing criticism from both sides of the aisle after he posted a meager tweet with his condolences for the family that failed to acknowledge the impact McCain has had on American political life, and his record as one of the nation's most celebrated war heroes.

A group of both supporters and protesters gathered outside the Trump National Golf Club in Sterling, Virginia, as the president arrived, holding Make America Great Again signs as well as others that say 'FAKE PRESIDENT' and 'RESIGN NOW'.

Soon after, Donald Trump Jr posted videos of his children teeing off at another Trump National Golf Club location in Westchester, New York.

The presidential sighting came amidst reports that the Commander-in-Chief has been left off the list of people McCain requested to attend his funeral months before he died after being locked in a war-of-words with Trump since 2015.

Those close to the Republican Arizona senator reportedly started making arrangements for McCain's funeral in May, nearly a year after he announced that he had been diagnosed with an aggressive and rare form of brain cancer.

He died on Saturday at his Arizona home surrounded by his family at the age of 81.

According to a report by the New York Times, McCain's inner circle said vice president Mike Pence was invited to the service but not Trump.

Donald Trump is not invited to Senator John McCain's funeral because of their long-standing feud, sources have revealed

The Times cited McCain's 'rocky relationship' with the president as the reason Trump was not on the invite list.

McCain reportedly spent the last year of his life planning his own funeral, CNN reported Saturday night. Friends of the senator said he wanted the service held at three locations: Arizona, the National Cathedral in Washington and Annapolis, Maryland.

Sources said that McCain had requested that George W Bush and Barack Obama deliver the eulogies at his funeral.

Two family members reiterated to CNN on Saturday that Trump won’t be present at the service.

Trump has not commented on McCain’s wishes that he stay away from the funeral, but did offer a short message on the senator’s passing.

‘My deepest sympathies and respect go out to the family of Senator John McCain,’ he wrote. ‘Our hearts and prayers are with you!’

Donald Trump and John McCain's public feud dates back to 2015. In a July 2015 tweet Trump bashed the Arizona senator, and their war of words continued for several years

Trump’s statement comes a little over a week after he failed to recognize McCain during a signing of the John S McCain National Defense Authorization Act, which lawmakers implemented to honor McCain’s leadership of the Senate Armed Services Committee and his years of service in the Senate.

During the ceremony Trump praised Rep. Martha McSally as ‘terrific’, but did not once mention McCain, even though the event was in his honor. McSally is seeking the Republican nomination for the Senate seat in Arizona.

At a June rally in Duluth, Minnesota Trump referenced McCain’s ‘no’ vote on the Affordable Care Act by giving a thumbs-down gesture and eliciting boos from the crowd. Meghan McCain fired back in a tweet that Trump’s attacks on her father ‘never stops being gross’.

Trump and McCain’s bad blood stems back to June 2015 when Trump announced he was running for president and called Mexican immigrants ‘rapists’ and drug runners during a speech.

McCain distanced himself from the future-president saying in an interview that he disagreed with Trump’s comment. Trump fired back by calling McCain ‘incompetent’ during a July 2015 rally at the Phoenix Convention Center.

The back and forth banter continued for the next two years, as Trump repeatedly launched public attacks – often times on Twitter – at McCain. In a 2016 tweet Trump slammed the senator as ‘foul mouthed’ and in a 2017 post he lashed out at McCain for voting against the Affordable Care Act.

‘3 Republicans and 48 Democrats let the American people down. As I said from the beginning, let ObamaCare implode, then deal. Watch!’ he wrote.

At one point during the two politician’s bitter feud, Trump mocked McCain’s record as a prisoner of war during the Vietnam War saying that McCain was only labeled a hero ‘because he was captured’ and he liked ‘people that weren’t captured’.

For his part, McCain publicly criticized Trump on numerous occasions. In a July statement, McCain lashed out at the president after Trump said during a meeting in Helsinki with Russian president Vladimir Putin that he accepted Russia’s claim that that they did not meddle in the US presidential election.

McCain said of Trump’s comments: ‘No prior president has ever abased himself more abjectly before a tyrant’.

McCain, who died at the age of 81, has also launched public attacks at Trump over the past several years

McCain again bashed Trump in March when Trump congratulated Putin on re-election.

‘An American president does not lead the free world by congratulating dictators on winning sham elections,’ McCain said.

The senator also wrote about his long-standing feud with Trump in his memoir The Restless Wave saying that Trump’s behavior was disturbing.

‘His lack of empathy for refugees, innocent, persecuted, desperate men, women, and children, is disturbing,’ the book read. ‘The way he speaks about them is appalling, as if welfare or terrorism were the only purposes they could have in coming to our country.’

‘His reaction to unflattering news stories, calling them “fake news,” whether they're credible or not, is copied by autocrats who want to discredit and control a free press,’ McCain wrote. ‘He has declined to distinguish the actions of our government from the crimes of despotic ones. He has showered with praise some of the world's worst tyrants.’
