Tucker Carlson accused Fox News host Mark Levin of “lobbying for war” at the White House on Wednesday, before warning President Donald Trump that a strike on Iran would “end his presidency.” “Mark Levin was at the White House today, lobbying for war with Iran,” claimed Carlson in a social media post. “To be clear, Levin has no plans to fight in this or any other war. He’s demanding that American troops do it.”
