Vice President JD Vance and Chairman of the Joint Chiefs of Staff Gen. Dan Caine both raised concerns about escalating the war in Iran as President Donald Trump weighed the possibility during a White House meeting on Friday, a source familiar with the matter and a US official told CNN. On Friday night, the US appeared to pause its bombing campaign on Iran after nearly two weeks of consecutive nights of strikes. Operations are "on a hold," a Department of Defense source told CNN on Saturday. On Friday, Caine specifically raised concerns about the US munitions stockpile and other potential negative implications, according to the sources.
