Mary Trump, the president's niece, ripped her cousin, Donald Trump Jr., while responding to news that Trump senior skipped his son's wedding.
"For those feeling sorry for Donny, Donny is a horrible human being," Mary said during an appearance on the Dean Obeidallah show. "He's a little Nazi. He's totally unaccomplished, and he's a racist and a misogynist and just a terrible person, so don't waste your time feeling bad for him."
Trump Jr. married his second wife on Thursday. The president earlier in the week suggested he might not make the wedding, saying it's "not good timing" as he's busy with Iran and the media will criticize him regardless.
Mary, who wrote a book about her uncle, added that Trump senior is "incapable of loving as well" and doubted his excuse.
"He plays golf several times a week, not just the weekends," she pointed out. "And he has massive amounts of time to talk to reporters."
She also speculated that "He just doesn't want to go because he can't stand his kid," and added, "Parents are supposed to go."
