The frustration culminated in a tense conversation Mr. Pottinger had with Vaughn Bishop, then the deputy C.I.A. director, and other officials in November. Mr. Pottinger urged the intelligence community to do more to cooperate with the Pentagon and other agencies. The next month, the National Security Council convened a deputy-level meeting across agencies to again push for further action and a broader investigation.

Mr. Pottinger declined to comment.

The Biden administration has tried to further improve coordination, including directing agencies to each name a coordinator to work on both identifying the cause of the episodes and improving health care for the injured personnel. Even some Democrats who have been briefed on the incidents called on the administration to be more aggressive.

“I don’t believe that we as a government, in general, have acted quickly enough,” said Representative Ruben Gallego, an Arizona Democrat and former Marine who heads the House Armed Services Subcommittee on Intelligence and Special Operations. “We really need to fully understand where this is coming from, what the targeting methods are and what we can do to stop them.”
