John McCain's youngest daughter Bridget has made a rare public statement in defense of her late father and slammed President Donald Trump in the process, calling him a 'child' and saying he wasn't invited to senator's funeral because 'you could not be counted on to be courteous.'

Bridget McCain, 27, offered her thoughts on the president's attacks on her father via her Twitter account, which her sister Meghan McCain then read Thursday morning on ABC's 'The View.'

'My little sister Bridget for the first time ever has decided that she wants to speak out,' Meghan McCain announced before sharing her younger sibling's reaction.

'Mr. Trump, everyone doesn't have to agree with my dad or like him, but I do ask that you be decent and respectful. If you can't do those two things, be mindful. We only said good-bye to him almost seven months ago. Even if you were invited to my dad's funeral, you would have only wanted to be there for credit and not for the condolences. Unfortunately, you could not be counted on to be courteous as you are a child in the most important role the world knows,' McCain read.

Trump complained during a visit to a manufacturing plant in Ohio on Wednesday that he didn't get thanked for giving McCain 'the kind of funeral that he wanted.'

'I endorsed him at his request and I gave him the kind of funeral that he wanted, which as president I had to approve. I don't care about this, I didn't get a thank-you. That's okay. We sent him on the way. But I wasn't a fan of John McCain,' Trump said.

The president was criticized after McCain's death for not keeping the flag flying at the White House at half-staff. It was eventually lowered and stayed that way until McCain was buried.

He was not invited to the funeral at the late senator's request. Former Presidents Barack Obama and George W. Bush gave the eulogies. A slew of political VIPs - Bill and Hillary Clinton, Michael Bloomberg, Joe Biden, Mitt Romney and others - were in attendance.

It was notable that Bridget McCain has broken her long public silence and weighed in on the matter. The youngest McCain child has stayed out of the national spotlight and rarely appeared with her father in his public life.

She did read a bible verse at her father's memorial service at North Phoenix Baptist Church this past August.

But she has otherwise stayed out of the public arena.

'It's very brave of her. She's young and she does not speak publicly,' Meghan McCain said on 'The View.'

She also noted her younger sister is 'very, very private.'

'Anyone who knows anything about political history could probably surmise why she's chosen to lead a very private life but she felt inclined to say and tweet this,' Meghan McCain said.

It was a rare public statement from Bridget McCain in defense of her father

During the 2000 Republican presidential primary, rumors were spread in South Carolina - before its decisive primary election - that Bridget was the illegitimate child of John McCain.

The McCains had actually adopted her as a baby from an orphanage in Bangladesh, when Cindy McCain was visiting the impoverished nation on a humanitarian visit and spotted Bridget.

During the 2000 primary, which George W. Bush eventually won, voters in South Carolina described receiving polling phone calls that asked them: 'Would you be more likely or less likely to vote for John McCain for president if you knew he had fathered an illegitimate black child?' in what was a reference to Bridget.

It's been Meghan McCain who has led the defense of her father from Trump's attacks. Her two brothers, Jack and Jimmy, serve in the military and McCain's children from his previous marriage have been quiet thus far.

'I don't like coming here every day and having to do this. It's extremely emotionally exhausting,' Meghan McCain admitted on 'The View' Thursday.

'I want to thank the American public for the decency and compassion they have given for us,' she added.

President Trump has spent the past week attacking the late senator, with whom he had a bitter relationship when McCain was alive.

The president also suggested on Wednesday that the Vietnam war hero should have come to him after he was first handed a copy of the infamous Golden Showers dossier, an unverified document that claims the Russians have black mail material on Trump.

'John McCain received the fake and phony dossier. Did you hear about the dossier? It was paid for by Crooked Hillary Clinton, right?' Trump said at the event in Ohio, drawing boos at the mention of his Democratic rival, who had a law firm fund opposition research after a conservative group first funded the research that became the dossier.

'And John McCain got it. He got it. And what did he do? He didn't call me. He turned it over to the FBI hoping to put me in jeopardy. And that's not the nicest thing to do,' Trump said.

McCain associate and former State Department official David Kramer testified in a court case that McCain gave the first pages of the dossier to former FBI Director James Comey on December 9, 2018.

The president's latest comments came as the McCain controversy boiled over after Trump's weekend attacks on the longtime senator who was held captive for 5 1/2 years in a Hanoi POW camp during the war.

In recent days the controversy has brought in McCain family members, the Senate leaders from both parties, and other lawmakers who knew McCain.

Senate Minority Leader Charles Schumer said he will reintroduce legislation to name a Senate office building after McCain – following Trump's comments that he is 'not a fan' of the Vietnam war hero.

Schumer first raised the issue after McCain's death in August. He brought it up again after Trump blasted McCain on Twitter over the weekend, then doubled down when asked about McCain in the Oval Office Tuesday.

'I was never a fan of John McCain, and I never will be,' Trump told reporters Tuesday.

Trump's continued public animosity has pushed several GOP senators to weigh in with their own views.

Senate Majority Leader Mitch McConnell came out with a tweet calling his 'good friend' and former colleague a hero – but did not directly call out Trump for his comments.

'Today and every day I miss my good friend John McCain. It was a blessing to serve alongside a rare patriot and genuine American hero in the Senate. His memory continues to remind me every day that our nation is sustained by the sacrifices of heroes,' said McConnell.

Sen. Lindsey Graham of South Carolina, who was McCain's best friend in the Senate and something of a protege, has been put on the spot by the situation. A former fierce Trump critic, Graham now backs Trump on a series of issues and has provided critical cover on the subject of the Russia probe.

'A lot of people are coming to John's defense now that called him crazy and a war-monger, so it's kind of interesting to see the politics of how this dispute's being used to bash Trump by people who were against both Trump and McCain,' said Graham in his home state, NBC reported.

Meghan McCain, meanwhile, delivered another emotional tribute to her father on ABC's 'the View' on Wednesday, punching back at Trump.

'If I had told my dad, 'Seven months after you're dead, you're going to be dominating the news and all over Twitter,' she said. 'He would think it was so hilarious that our president was so jealous of him that he was dominating the news cycle in death.'

Then she tried to turn the tables by bringing up cyber bullying – a top issue of first lady Melania Trump.

'Do not feel bad for me and my family,' she said. 'We are blessed. We are a family of privilege. Feel bad for people out there who are being bullied that don't have support.'

She continued: 'Feel people out there who are being bullied who don't have support ... There are kids committing suicide bc of cyber bullying on line. There are people going through rough time. ... We have 20 veterans a day committing suicide. Focus on these issues,' she said.

Trump attacked the late senator twice this weekend on Twitter, focusing on McCain's ties to the infamous Steele dossier.

'So it was indeed (just proven in court papers) 'last in his class' (Annapolis) John McCain that sent the Fake Dossier to the FBI and Media hoping to have it printed BEFORE the Election. He & the Dems, working together, failed (as usual). Even the Fake News refused this garbage!, the president wrote on Sunday.

McCain was actually fifth from the bottom of his class at the Naval Academy, and regularly joked about his own academic performance.

On Monday, Meghan McCain slammed Trump for having a 'pathetic life' for spending his weekend tweeting criticism of her father.

'He spends his weekend obsessing over great men, because he knows it, and I know it, and all of you know it, he will never be a great man,' McCain said on ABC's 'The View.'

'My father was his kryptonite in life. He was his kryptonite in death,' she added.
