“My father was his kryptonite in life. He’s his kryptonite in death,” she added.

The president over the weekend renewed his attacks on John McCain, who died in August months after he was diagnosed with brain cancer. He took aim at the late senator over reports that one of the then-senator's associates had shared a dossier of allegations about Trump's ties to Russia with the media.

"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," Trump tweeted on Sunday. "He & the Dems, working together, failed (as usual). Even the Fake News refused this garbage!"

On Saturday, the president said McCain had "far worse stains" than spreading the dossier, invoking his vote that helped doom a GOP effort in 2017 to repeal the Affordable Care Act.

Trump has long criticized McCain, dating back to before he took office. His latest tweets drew rebukes from McCain's family, friends and former colleagues in the Senate.

Meghan McCain on Monday explained her initial Twitter response in which she urged the president to spend more time with his family rather than tweeting about the late senator, describing how she would go fishing and hiking with her father.

“I just thought, ‘Your life is spent on your weekends not with your family, not with your friends but obsessing — obsessing — over great men you could never live up to,’” she said. “That tells you everything you need to know about his pathetic life right now.

"I genuinely feel bad for his family," she added.
