A joint military exercise between the United States and South Korea scrapped after President Donald Trump griped about "tremendously expensive" military drills would have cost around $14 million, U.S. officials said Friday.

The Pentagon announced last month that it was indefinitely suspending the Freedom Guardian military exercise in support of the Singapore summit between Trump and North Korean leader Kim Jong Un.

Trump repeatedly touted the cost savings that will come with his decision to stop "the war games," in a surprise concession to Kim at the June 12 summit to discuss Pyongyang's nuclear disarmament.
