Meghan McCain Tells Mary Trump 'Leave Me and My Entire Family The F*** Alone'

The McCains and the Trumps continue to fire shots at each other ... and this time it's pitting John McCain's daughter against Donald Trump's niece.

Meghan McCain went scorched-earth on Mary Trump Monday after the former President's niece took a shot at her on "The View."

Mary, who secretly recorded her relatives for a book she wrote, beamed into the talk show for an interview about her famous family members, and she ripped Meghan for not being part of the discussion, saying it showed a lack of courage on MM's part.

Well, Meghan didn't take the dig too kindly and now she's going after Mary and the rest of the Trumps, saying ... "There is no 'good' Trump family member to me. Continue to wish they would all just leave me and my entire family the f*** alone."

It's unclear why Meghan was not part of the segment with Mary ... Meghan appeared in earlier segments of the show, but Mary was only fielding questions from Whoopi Goldberg, Joy Behar, Sara Haines and Sunny Hostin.
