"Let him go get a television network and say it so that people listen," the president fired off at the former Fox News star.

Israel and Iran have begun a new round of attacks, as the conflict between the two heavily armed rivals enters its fourth day.

Donald Trump's former national security adviser said Israel's attacks could make a nuclear deal more likely. Trump said on Truth Social that Iranians should evacuate their capital city of Tehran. To completely destroy Iran's nuclear facilities, Israel will likely need U.S. bomber planes.

President Donald Trump vetoed a plan presented to the U.S. in recent days to kill Iranian supreme leader Ayatollah Ali Khamenei, according to a U.S. official familiar with the matter.

Iranian officials have warned that U.S. participation in an attack on its facilities will imperil any chance of the nuclear disarmament deal the president insists he is still interested in pursuing.

After canceling negotiations with the U.S. scheduled for Sunday, Tehran has signaled it is willing to talk.

Tehran has asked Qatar, Saudi Arabia and Oman to press U.S. President Donald Trump to use his influence on Israel to agree to an immediate ceasefire with Iran in return for Tehran's flexibility in nuclear negotiations,
