Is this the latest example of “fake news” the US President often derides?:

President Donald Trump has requested options for reducing the number of US troops in South Korea, the New York Times reported late Thursday, citing several people briefed on the matter.

The President’s request of the Defense Department comes ahead of his highly anticipated sit-down with North Korean leader Kim Jong Un, expected to take place along the demilitarized zone (DMZ) between the two Koreas.
North and South Korea recently held their own historic summit, which included an agreement on holding talks over denuclearizing the Korean Peninsula and bringing a formal conclusion to the Korean War.
If the peace talks continue among countries, it could decrease the need for a US presence in the region, officials told the newspaper.
National security adviser John Bolton on Friday disputed the Times’ report, calling it “utter nonsense.”
“The President has not asked the Pentagon to provide options for reducing American forces stationed in South Korea,” Bolton said in a statement. The Department of Defense also denied the report in a statement.  [CNN]
