Espionage Expert Warns Trump Administration Alarmingly Simple to Spy On as Foreign Intelligence Services Target Mar-a-Lago and Unqualified Appointees

BLUFPersistent unsecured communications and unvetted physical access at Mar-a-Lago hand adversary services a collection environment no counterintelligence posture can offset while both vulnerabilities remain open.

Harvard Kennedy School espionage expert Calder Walton wrote in a column for iNews that Trump is likely more surveilled by foreign intelligence services than any prior US president, citing his widely known mobile number and habit of taking calls from journalists who cold-call for interviews 123. Walton assessed that Russia, China, and Israel are "almost certainly" listening to Trump's conversations, and that any capable foreign service would have recruited agents at Mar-a-Lago given the resort's documented security lapses, including classified documents found in a bathroom during Trump's first term 23. Walton distinguished friendly-state intelligence collection from hostile-state activity, noting adversaries also use espionage, subversion, and sabotage to influence a target rather than merely gather information 23. Walton also criticized the qualifications of senior Trump intelligence appointees, including Defense Secretary Pete Hegseth, FBI Director Kash Patel, former DNI Tulsi Gabbard, and DNI nominee Jay Clayton 1.

Analysis
Foreign intelligence access to Trump's unsecured communications and Mar-a-Lago grounds persists unchecked, given the phone number's continued availability to journalists and no reported change to the resort's access controls. Adversary services gain a standing psychological-profiling advantage over friendly-state collectors, since hostile intelligence pairs signals access with subversion and sabotage tradecraft rather than passive listening. The appointee criticism functions as a second, distinct vulnerability: leadership assessed as unqualified is more exploitable through flattery, misdirection, or recruitment approaches than leadership with deep institutional grounding.
