"I know what is right and what is wrong and what is true and not true", she said. In an interview with ABC News's Tom Llamas that is set to air Friday night, Melania discussed her husband's alleged infidelity.
When asked whether that statement was accurate, Melania said, "I never talked to Mr. Giuliani", noting that she doesn't know why he made that statement.
When asked if the rumours had hurt her, she paused.
Trump's second wife visited the countries of Ghana, Malawi, Kenya and Egypt during the trip, having previously only ever travelled overseas for official visits alongside her 72-year-old husband. Then she reiterated the "media world is speculating".

Mum-of-one Melania can speak more languages than any other First Lady before her: English, French, German, Italian, Serbian and of course her mother tongue, Slovenian.
"Before we go, I do want to say something". Daniels later risked violating the hush agreement by sharing details of her 2006 alleged affair with Donald Trump in a CBS "60 Minutes" interview in March. "I really love to live in Washington and the White House", she said. It's what media speculate, and it's gossip.
She insisted allegations of her husband's infidelities are not a concern. "It also makes them want to label her as a "victim" and as a 'prisoner" of Donald's.
Melania also said there are people now in the White House she doesn't trust and who do not have her husband's best interests in mind. "I know", she adds, pointedly.
Like past first ladies, Melania also faces criticism of her fashion choices, which lean toward well-cut, refined but not flashy clothes from Ralph Lauren and French-American designer Herve Pierre.
