Melania Trump Says Rumors of Donald Trump Cheating Are Just Gossip

Melania Trump brushes off allegations that her husband, Donald Trump, has had affairs with women ... saying it's just gossip orchestrated by the media.

The First Lady sat for an interview -- her first solo interview since taking up residence in the White House -- with ABC News. She dismissed claims, notably by Stormy Daniels and Karen McDougal, that the Prez has strayed during their marriage.

Melania says, "I'm a mother and a First Lady, and I have much more important things to think about and to do."

She added, "It is not concern and focus of mine."

Melania also said there are people currently in the White House she doesn't trust and who do not have her husband's best interests in mind.

The full interview airs Friday night at 10 PM ET.
