WASHINGTON: An unprecedented pre-presidential inauguration feud between Donald Trump and intelligence agencies that soon will be under his command could harm US security if not quickly defused, current and former government officials said. They said the morale at the Central Intelligence Agency (CIA) and other agencies was already sagging because of disputes with Trump over whether Russian President Vladimir Putin ordered interference in the US election and over leaks about an unsubstantiated dossier compiled by a private security firm suggesting Moscow had compromising information on Trump. Unless addressed, the disputes could prompt the departure of personnel and lead those who remain to take fewer risks to counter security threats, the officials said. In the last few months, Trump has expressed his willingness to deal with Putin and denigrated the work of the intelligence agencies. This week, the president-elect accused agencies of leaking the dossier’s information to the media, but National Intelligence Director James Clapper said he did not believe intelligence officials were responsible for the leak. “People shooting at (the CIA) is pretty common. But usually it’s not the president,” a former senior US official said. Trump’s transition team did not reply to email messages seeking comment. “I think it’s a recipe for disaster,” said Daniel Benjamin, who served in senior White House and State Department counterterrorism posts under Democratic presidents. Benjamin, now at Dartmouth College, said there was a “strong chance” people would leave and they have “tremendous value” to the private sector. Complicating the situation just a week before Republican Trump is sworn in, two of his nominees for top security posts set a different tone at their Senate confirmation hearings, heaping praise on the men and women who work in the secret world of intelligence gathering. Republican congressman Mike Pompeo, nominee for Central Intelligence Agency director, said on Thursday that he had seen CIA personnel “walk through fire”. Separately, Trump’s nominee for US defence secretary James Mattis told senators that he had a “very, very high degree of confidence” in US intelligence agencies. Mattis also put Russia at the top of a list of threats to US interests. A top official at an intelligence agency said a growing number of intelligence officers over the age of 50 and with at least 20 years of service, including at least five years overseas, had drafted and, in many cases, signed but not dated their resignation letters. “There is great anxiety here about the president-elect’s apparent disdain for the work we do and the dangers we face,” a second senior intelligence official, at another agency, said. He and others spoke on the condition of anonymity to discuss intelligence matters and morale at their agencies. The latest round of resentment began with a CNN report that Trump had been briefed on January 6 by intelligence and law enforcement chiefs on a two-page memo summarising the unverified claims in the dossier. In blaming intelligence agencies for the leak, Trump wrote on Twitter, “One last shot at me. Are we living in Nazi Germany?” Spy chief Clapper called Trump before dinnertime on Wednesday to calm the waters. Trump and Clapper differed on what was said in the phone conversation. On Friday, Trump appeared to again blame US spies for the leak. “Probably released by ‘intelligence’ even knowing there is no proof and never will be,” he said on Twitter. US intelligence agency personnel “are kind of shell-shocked at being accused of being Nazis and intentionally leaking this stuff”, the former senior official said. The 17 US intelligence agencies have combined budgets of more than $70 billion and tens of thousands of employees. They are responsible for everything from warning of terrorist attacks to supporting American troops on the battlefield and analysing the impacts of global trends such as climate change.
