John Ratcliffe, CIA director-nominee, told the Senate Select Committee on Intelligence on Wednesday that he will aggressively review CIA analysis on the mysterious conditions suffered by overseas intelligence personnel and whether they were by enemy-directed energy weapons.

“Should I be confirmed as CIA director, I will review all existing information and analysis and pursue all leads that provide insight into the cause and origin of [anomalous health incidents] and all medical incidents with a [counterintelligence] nexus,” Mr. Ratcliffe said in written answers to questions from the committee. “I will ensure that, under my leadership, CIA will pursue this issue aggressively, objectively, and with total analytic integrity.”

The CIA has come under fire from victims of the mysterious malady called “Havana Syndrome,” first detected in 2016 by U.S. Embassy personnel in Cuba. The CIA is leading other intelligence agencies in concluding that it is unlikely that the affliction is caused by foreign adversaries.

Last week, however, the Office of Director of National Intelligence published an updated analysis that revealed two unspecified U.S. intelligence agencies changed their views on the origin of the syndrome.

The two agencies now believe it is possible that directed energy weapons, including radio frequency arms, could be behind at least some of the incidents that have affected an estimated 1,500 American diplomats, intelligence personnel and some military attaches.

A subcommittee of the House Permanent Select Committee on Intelligence recently issued an interim report that stated that new evidence points to foreign adversary attacks for incidents known as AHIs.

The report also accused the CIA of using faulty analysis and for obstructed the panel’s investigation into the origin of AHIs. The CIA denied both charges.

The written answers were made public during Mr. Ratcliffe’s nomination hearing before the Senate committee.
