In an interview broadcast on Wednesday, Trump was asked whether he had called the longtime Israeli leader "effing crazy" and accused him of ingratitude, paraphrasing a report by Axios.
"I did," Trump told the Pod Force One podcast.
"I wouldn't say angry. I was a little bit perturbed at his constantly fighting with Lebanon, you know."
Trump went on to say he and Netanyahu get along very well.
According to the Axios report, which cited an unidentified US official, Trump said to Netanyahu in a call on Monday: "You're f***ing crazy. You'd be in prison if it weren't for me. I'm saving your ass. Everybody hates you now. Everybody hates Israel because of this."
Trump said in the interview: "At some point I said, Bibi, we got to stop this. We got to stop it."
Iran has said it will not agree to a deal with the United States to end the war that Trump and Netanyahu launched in late February, unless a ceasefire also covers Lebanon, which Israel invaded in March in pursuit of the Iran-aligned Hezbollah militia that fired across the border in support of Tehran.
Hostilities have continued despite a US-mediated agreement announced on Monday that led Israel to step back from attacking the Hezbollah-controlled southern suburbs of Beirut, and the Iran-backed group to halt cross-border strikes.
Israeli drone strikes killed at least six people in southern Lebanon and targeted a car just south of Beirut on Wednesday, Lebanese security sources said, while Israel said it intercepted a hostile aircraft likely fired by Hezbollah.
Trump bristled when asked if Netanyahu "tricked" him into attacking Iran, saying his critics were "the enemy".
Trump has used expletives about Israel in the past, including publicly saying last year that Israel and Iran "don't know what the f*** they are doing".
