Donald Trump Jr. sharply criticizes Sen. Ted Cruz (R-Texas) after Cruz denounces a U.S.-Iran memorandum of understanding related to Iran’s reconstruction efforts. In a Wednesday post on X, Trump Jr. says Cruz is “lying thru his teeth” and disputes Cruz’s characterization of the memorandum. The dispute reflects continuing infighting within the Republican Party over how the administration’s approach to Iran is being framed and whether it aligns with Trump-aligned priorities.

According to the reports, Cruz previously criticized the memorandum of understanding that would allow for investment connected to rebuilding in Iran, arguing against the policy. Trump Jr. responds by accusing Cruz of misinformation and suggesting Cruz is not aligned with the broader “MAG A” agenda. The exchanges come as Republicans debate the terms and implications of the proposed U.S.-Iran understanding and how it should be discussed within the party.
