(CNN) President Donald Trump again attacked late Sen. John McCain Saturday -- prompting the Arizona Republican's daughter Meghan McCain to respond that "no one will ever love" Trump the way they loved her father.

Trump's recent attack on McCain, who passed away in August, is the latest in his years-long offensive feud against the late senator, this time targeting McCain's ties to the controversial Russia dossier and his vote against repealing Obamacare.

"Spreading the fake and totally discredited Dossier 'is unfortunately a very dark stain against John McCain,'" Trump tweeted , quoting Ken Starr, the independent counsel who investigated then-President Bill Clinton.

Starr called the dossier "a very dark stain" against McCain in an interview Saturday on Fox News, but also called McCain "a great man" and "an American hero."

The comments referred to a series of memos written in 2016 by retired British spy Christopher Steele. They alleged a widespread conspiracy of collusion between the Trump campaign and the Kremlin, which both sides deny. The most salacious and damning allegations in the dossier remain unverified to this day. But the claims that form the bulk of the memos have held up over time , or at least proved to be partially true.
