McGurk said on Twitter: "Trump said that nothing happened after he abandoned north-east Syria and handed it over to Putin and Erdogan, but according to a new UN's report, war crimes, murders, kidnappings, looting and forced displacement occurred in the areas our soldiers left and the matter is getting worse."
McGurk added: "US forces are currently in Syria, but not to protect the people there, nor to fight ISIS, but (according to Trump) to guard the oil."
He added: "These forces are now under pressure, and they are even injured by the Russian forces when Trump ordered his forces to leave.".
He added: "The supreme leader (Trump) has no idea about what the American soldiers are exposed to there, and he does not care about this matter. Trump has inherited a stable and permanent mission and burned it."
