Trump said Sunday he was "very disappointed" in NATO, accusing allies of abandoning the US during the Iran conflict that began in February.
The remarks follow a tense 9 April meeting with NATO Secretary-General Mark Rutte and White House plans to relocate troops from uncooperative allies, per The Wall Street Journal.
Congress passed a 2023 law blocking any president from leaving NATO without legislative approval, and no formal withdrawal process has begun, according to Politico.
