President Donald Trump said this week that he wouldnt have allowed the CIA to recruit Kim Jong Uns family members as informants to spy on the North Korean dictator. The pronouncement marked the latest instance in which the president has appeared to side with a foreign adversary over the U.S. intelligence community.

Speaking to reporters at the White House on Tuesday, Trump responded to reports that Kims estranged half-brother, Kim Jong Nam, had been working with the CIA prior to his murder in February 2017. Trump claimed he knew nothing about the allegations, but said such spying would not have happened on his watch.

I know this: that the relationship [with Kim] is such that that wouldnt happen under my auspices, Trump said, according to CNN .

The president added that hed received a beautiful letter from Kim and that he believed the North Korean leader had kept his word on suspending nuclear and missile testing. Trumps remarks contradicted his own national security advisers assertion, made earlier in the day , that Kim was violating the terms agreed upon at the 2018 summit in Singapore.

Kim Jong Nam died after being attacked with VX nerve agent in Kuala Lumpur International Airport in Malaysia. The Wall Street Journal reported Monday that the dead man had been a CIA informant whod traveled to Kuala Lumpur from his home in Macau to meet with a contact from the intelligence agency.

A book by Washington Post reporter Anna Fifield published on Tuesday corroborated this claim. According to The Great Successor, Kim Jong Nam had provided information about the North Korean regime during meetings with American spies. Fifield said the informant had traveled to Singapore and Malaysia on a number of occasions to meet his handlers.

The CIA has yet to respond to the reports.

The presidents comments about the agencys alleged methods have raised concerns that he could be stripping the U.S. intelligence community of an important tool.

Trump just crippled the CIAs ability to recruit high-placed sources, tweeted Frank Figliuzzi , a former assistant director at the FBI.

Susan Rice, a national security adviser during former President Barack Obamas tenure, also lambasted Trumps remarks.

America, this tells you all you need to know about our so-called Commander-in-Chief, Rice wrote.

Jung H. Pak, a Brookings Institution senior fellow and former U.S. intelligence official, told Reuters that Trump needs to understand that to keep the nation safe, agencies like the CIA need to be able to do its job gathering and analyzing intelligence that will support the full range of diplomatic, military, and economic policies and initiatives.

[An] untold number of CIA officers, staff, and others put their lives on the line to get the best intel to protect our national security, she later tweeted.

Trump has publicly clashed with U.S. intelligence agencies in the past.

Last year, he said he believed Vladimir Putins assertions that Russia had not interfered in the 2016 presidential election despite U.S. intelligence proving otherwise.
