"Trump said that he “never mentioned the word or the name Israel” in his conversation with Russia’s foreign minister and ambassador."

Taken at literal/face value that could very well be true, but that doesn't preclude the Russians from figuring out by way of example that a reference to "Mossad" doesn't mean a British intelligence agency was the source or that a casual word/name drop of any number of Israeli cities might hint at locale!

I can understand another American President saying and believing, "I did not have sex with that woman" because in that fundamentalist "christian" bible thumpin' land below, sex was probably considered for decades as only performed on a bed in the missionary position under cover of sheets or darkness and loss of virginity in the front or back seat of a car watching submarine races and best described by Meatloaf in Paradise by the Dashboard Light!

Many Americans will still call a Canadian a liar if told our milk comes in bags and yet believe Donald :)
