Presumptive Republican presidential nominee Donald Trump may not get the same level of briefing on intelligence that President Barack Obama receives, a White House spokesman said Thursday.

“The decisions about how and whether and when and what to brief to the presidential nominees is a decision that will be made by our intelligence professionals,” White House spokesman Josh Earnest said Thursday.

Those decisions, Earnest said, will be made by James Clapper, the director of national intelligence.

Clapper told reporters last week that a plan for the candidate briefings is already in place. The candidates are due to start receiving intelligence briefings after they are formally nominated.

A report in The Daily Beast said there were concerns in the intelligence community that Trump will spill secrets — possibly by accident, given his informal way of speaking — that he gets from classified briefings.

Earnest said the intelligence community “is committed to fulfilling the spirit of nonpartisan cooperation when it comes to sensitive national security issues.”

He added: “they also will carry out those activities consistent with their understanding about treating this information sensitively,” he said.

Bruce Reidel, who worked for 30 years at the Central Intelligence Agency and is now at the Brookings Institution, said while the two nominees get some briefings before the election, the real briefing period only starts after the election.

“Very little information on intelligence operations or methods is provided until you are elected President,” Reidel said in an emailed response to a question.
