WASHINGTON — Two days after President Trump’s summit with Russian President Vladimir Putin, Russian officials offered a string of assertions about what the two leaders had achieved.

“Important verbal agreements” were reached at the Helsinki meeting, Russia’s ambassador to the United States, Anatoly Antonov, told reporters in Moscow on Wednesday, including preservation of the New Start and INF agreements, major bilateral arms control treaties whose futures have been in question. Antonov also said that Putin had made “specific and interesting proposals to Washington” on how the two countries could cooperate on Syria.

But officials at the most senior levels across the U.S. military, scrambling since Monday to determine what Trump may have agreed to on national security issues in Helsinki, had little to no information Wednesday.

At the Pentagon, as press officers remained unable to answer media questions about how the summit might impact the military, the paucity of information exposed an awkward gap in internal administration communications. The uncertainty surrounding Moscow’s suggestion of some sort of new arrangement or proposal regarding Syria, in particular, was striking because Gen. Joseph Votel, who heads U.S. Central Command, is scheduled to brief reporters on Syria and other matters Thursday.

Defense Secretary Jim Mattis did not attend Wednesday’s Cabinet meeting with Trump and has not appeared in public this week or commented on the summit.

Current and former officials said it’s not unusual for it to take at least several days for aides to finalize and distribute internal memos documenting high-level conversations. Adding to the delay in the case of Trump’s Russia summit is the fact that the president’s longest encounter with Putin, a two hour-plus session, included no other officials or note-takers, just interpreters.

Trump continued to praise his private meeting with Putin and an expanded lunch with aides as a “tremendous success” and tweeted a promise of “big results,” but State Department spokeswoman Heather Nauert said the administration was “assessing … three takeaways,” which she characterized as “modest.” They were the establishment of separate working groups of business leaders and foreign policy experts, and follow-up meetings between the national security council staffs of both countries.

White House spokeswoman Sarah Huckabee Sanders listed a number of topics that had been discussed, including “Syrian humanitarian aid, Iran’s nuclear ambition, Israeli security, North Korean denuclearization, Ukraine and the occupation of Crimea, reducing Russian and U.S. nuclear arsenals, and of course, your favorite topic, Russia’s interference in our elections.”

But while Trump told lawmakers this week that he and Putin had made “significant progress toward addressing” these issues and more, neither Sanders nor any other U.S. official from Trump on down has offered specifics on what was accomplished on those subjects beyond what she called “the beginning of a dialogue with Russia.”

Asked about calls from congressional Democrats for testimony from the U.S. interpreter, Sanders said it was a question for the State Department. Nauert said that there was no precedent for such a demand and that there had been “no formal request” for such an appearance. “Overall, as a general matter,” she said, “we always seek to work with Congress, and that’s all I have on this, OK?”
