WASHINGTON – President Donald Trump again railed against late Republican Sen. John McCain on Thursday, calling the Vietnam veteran's vote against a skinny repeal of Obamacare "disgraceful."

In an interview with Fox News' Sean Hannity, Trump brought up McCain, the Arizona senator who died last August, while discussing future plans to reshape health care and the future of the Affordable Care Act. Trump said Republicans had a plan done but it was shot down due to McCain.

Then, Trump rekindled the infamous moment in 2017 when McCain voted against a Republican-led effort to repeal portions of Obamacare, walking to the front of the Senate floor and giving a thumbs-down gesture.

"He did the Republican Party a tremendous disservice and he did the nation a tremendous disservice, tremendous, and it’s unfortunate," Trump said of McCain, the Republicans' 2008 presidential nominee. "He went thumbs-down at the very last moment and I thought it was a disgraceful thing to do and very, very bad for our country and bad for health care."

Despite widespread criticism, even from members of his own party, Trump has continued to assail McCain even after his death. Before he died, McCain took a stand against Trump's rhetoric, which he said had swayed Republicans from their true beliefs.

Last month, Trump said he was "never a fan" of the late senator, tweeted incorrectly that McCain tried to publicize a dossier alleging misdeeds by Trump and boasted that he never got a thank-you for giving McCain "the kind of funeral that he wanted."

McCain's daughter, Meghan, responded to some of the president's attacks by questioning why he was so obsessed with her father and saying that the president would "never be a great man" like McCain.

"No one will ever love you the way they loved my father," Meghan McCain said in one tweet.

Trump then defended his attacks by blaming the media.

"I don't talk about it. People ask me the question, I didn't bring this up," the president told Fox News host Maria Bartiromo last month after she questioned why Trump was attacking a dead man who "can't punch back."

On Thursday, however, Trump was the one to bring up McCain during a discussion on the future of health care.

"It was done and then John McCain, at the very last moment, late in the evening, went thumbs-down and everybody said, 'What was that?'" the president told Hannity.

Trump added that Republicans would be looking toward another solution soon but said first they would need to take back control of the House, which shifted power to Democrats after the 2018 midterms.

"We’re going to do things that nobody has ever seen on health care, but we have to get back the House," Trump said.
