Trump has the power to declassify anything, but sharing information without permission of the ally who provided it represents "a major breach of espionage etiquette, and could jeopardize a crucial intelligence-sharing relationship," according to the New York Times. 

Buzzfeed News later reported that two officials have confirmed the report, indicating that "it's far worse than what has already been reported."

At least one member of the Senate Intelligence Committee had been briefed on Trump’s disclosures, according to BuzzFeed News. The outlet also reported that other members have said they did not get a briefing.
