In a statement released after Trump arrived at the NATO military alliance, the president said he would seek an official review to stop leaks that he said posed a serious security threat.
"The alleged leaks coming out of government agencies are deeply troubling," Trump said in the statement. "I am asking the Department of Justice and other relevant agencies to launch a complete review of this matter, and if appropriate, the culprit should be prosecuted to the fullest extent of the law."
He said the relationship between the United States and Britain was the most cherished of all US ties.
