Republican presidential nominee Donald Trump will receive his first classified intelligence briefing from the White House on Wednesday.
NPR and other news organizations reported that Trump will most likely be briefed at FBI headquarters in New York by the Office of the Director of National Intelligence.
Trump will be accompanied by two advisors to his campaign: retired Lt. Gen. Michael Flynn, who is the former director of the Defense Intelligence Agency, and New Jersey Gov. Chris Christie, a former federal prosecutor.
The sitting president has offered classified briefings to the two presidential candidates from each major party since President Harry Truman extended the courtesy to Dwight D. Eisenhower and Adlai Stevenson in 1952.
While the briefings do contain classified information, they are more of an overview than an in-depth briefing, and do not contain details like who collected intelligence, nor does it contain information about covert operations.
The president-elect does receive a robust daily intelligence briefing after the general election. That briefing is identical or very similar to the one the president and top administration officials receive, which is called the President's Daily Briefing, or PDB.
It's not known if Democratic presidential candidate Hillary Clinton has received an intel briefing. In July, the director of National Intelligence James Clapper said that both candidates would receive briefings, despite doubts expressed publicly by some Republicans and Democrats regarding the trustworthiness of the opposing party's candidate.
"We will brief both candidates if they want it," he told the Aspen Security Forum.
