The US president also said he wanted to bring Khashoggi's fiancee, Hatice Cengiz, to the White House.
According to the intercepts, Saudi officials close to crown prince Mohammed bin Salman had tried to lure Khashoggi back to his home country with the promises of a lucrative job offer and offers of protection.
But Turkish officials have concluded that whatever the intent of the operation, Khashoggi was killed inside the consulate.
"There's something really awful and disgusting about that, if that was the case, so we're going to have to see", Trump said.
Khashoggi has been a prominent critic of Riyadh and a US resident who has written columns for the Washington Post.
Cengiz described how hard it was, in the middle of dealing with Khashoggi's disappearance, to have to cancel all their wedding preparations.

Khashoggi, a former Saudi government adviser, had been living in the United States since previous year fearing arrest.
Khashoggi has been missing ever since cameras captured him going inside the Saudi consulate in Istanbul on October 2.
In an article for the Washington Post, Ms Cengiz pleaded with Mr Trump and his wife Melania to "help shed light" on the disappearance of her partner.
