Donald Trump Jr. criticizes Republican Sen. Ted Cruz after Cruz makes comments about the Trump administration’s proposed memorandum of understanding involving Iran. According to reports, Trump Jr. posts on X that Cruz is “lying through his teeth,” framing Cruz’s statements as inaccurate. The dispute reflects continuing infighting within the GOP over the administration’s approach to Iran and the terms under discussion. Cruz had publicly challenged the president’s proposed Iran deal, and Trump Jr.’s response targets the credibility of Cruz’s remarks. The exchanges underscore a broader split among some Republicans about how the administration should negotiate or structure an agreement related to Iran. Neither outlet provides additional details in its excerpt beyond the character attack and the fact that Cruz has criticized the proposed deal and that Trump Jr. responds directly to those comments. The conflict remains ongoing as lawmakers continue to debate the proposed Iran framework and its implications.
