Ted Cruz criticizes JD Vance’s ‘terrible’ deal with Iran as he teases a run for president in 2028
Senator Ted Cruz has criticised Vice President JD Vance's negotiation of a memorandum of understanding with Iran, calling it "a terrible deal," as he signals interest in a possible 2028 presidential run. Cruz, who lost the 2016 Republican nomination to Donald Trump, has also said the party has not yet united behind Vance as its heir apparent, suggesting there would be a broader debate within the GOP about its future direction. The remarks matter because they expose early cracks in Republican unity over succession planning, with several senior figures positioning themselves ahead of the next primary race.
Cruz has been touring Iowa, an early primary state, gauging support for a potential campaign, and is separately promoting a new book about Supreme Court Justice Clarence Thomas. He has also criticised Vance's continued friendship with broadcaster Tucker Carlson amid antisemitism allegations against him. Vance, asked about Cruz's ambitions during a White House briefing, called him "authentic and likable" but urged Republicans to focus on the midterms rather than 2028, while allies dismissed Cruz as no serious threat. Secretary of State Marco Rubio, also seen as a contender, has said he would not run if Vance does, and Trump himself has remained noncommittal about backing Vance, saying it is "way too early" to weigh in.
In short
- Cruz calls Vance's Iran memorandum "a terrible deal" amid 2028 rivalry
- Cruz says GOP hasn't united behind Vance for 2028 nomination
- Vance urges focus on midterms; Trump remains noncommittal on backing him
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Cruz’s criticism can be seen as a legitimate challenge to a consequential agreement: Republicans should scrutinise whether its terms protect US security and address concerns about Iran, rather than assume the vice president’s negotiations deserve automatic support. A contest over the party’s future could also let voters compare candidates’ foreign policy and leadership before choosing a successor.
The case against
Vance’s defenders could argue that diplomacy requires compromise and that condemning the memorandum as “terrible” without examining its terms risks turning a complex security question into campaign rhetoric. They may also see Cruz’s early positioning and attacks on Vance as distracting Republicans from immediate priorities, including the midterms, before the party needs to settle on a 2028 nominee.
Explained simply
The Republican Party is the main conservative party in the United States. Its presidential candidate is chosen through state contests called primaries, and Iowa is traditionally one of the first states to vote, making it an important place for hopeful candidates to build support.
Ted Cruz is a Republican senator from Texas who ran for the party’s presidential nomination in 2016, when Donald Trump won. JD Vance is Trump’s vice-president, while Marco Rubio is secretary of state; all three are prominent figures whose future role in the party is being discussed.
The debate matters because Republicans have no settled successor to Trump, and a contest for the 2028 nomination could shape the party’s direction. Iran is a long-running focus of US foreign policy, so disagreements over negotiations with its government can also expose differences among Republican leaders.
