Trump vows revenge on Iran and what to watch in Arizona’s primaries: Morning Rundown - NBC News

What the report says

NBC News reported that President Donald Trump is facing a volatile phase in the U.S. conflict with Iran after three American service members were killed since Friday. The outlet said Trump has promised retaliation, while a senior White House official characterized the situation as a period of uncertainty after an April ceasefire broke down and a more recent memorandum between the two countries unraveled.

According to NBC, U.S. Central Command announced additional strikes Monday afternoon. The Defense Department identified two soldiers killed in Iranian attacks in Jordan as Tyler James Feehan, 25, of Hawaii, and Isabella Gonzales, 19, of Texas. NBC reported that another U.S. service member died in a separate attack in Iraq. The report framed the escalation as both a military and political test for Trump, with Iran needing primarily to endure rather than defeat the United States outright, and the White House under pressure to show Americans a path toward ending the war.

The Morning Rundown also previewed Arizona’s primaries, which NBC described as important for shaping competitive fall races in a battleground state. In the governor’s race, Republican Rep. Andy Biggs was described as the front-runner, while Democrats see an opening if the GOP nominates a Trump-aligned candidate to challenge Gov. Katie Hobbs. NBC also noted that the secretary of state contest could draw national attention because the winner will oversee elections in the swing state in 2028.
