Donald Trump and Hillary Clinton will start receiving classified intelligence briefings by early next week.

The official confirmation is pending Clinton's securing the Democratic Party's nomination at the Philadelphia convention. Trump was named the nominee last week in Cleveland.

"The briefings are traditionally given after nominating conventions have identified all the candidates," a senior intelligence official told ABC News.

Sharing classified information on national security with the Republican and Democratic nominees dates back to 1952. Since then, each party's ticket, including the candidate's running mate, will receive updates from the director of national intelligence as a means of preparing the winner to assume office in January.

Republicans may be disappointed by the news after some GOP leaders had called National Intelligence Director James Clapper to deny Clinton the clearance for her mishandling of classified information as secretary of state.

"Briefings for the candidates will be provided on an even-handed, non-partisan basis," the DNI said in response to House Speaker Paul Ryan earlier this month.
