WASHINGTON (CNN) - Sen. Barack Obama Tuesday received his first high level briefing as a candidate from the office of the Director of National Intelligence, according to officials at the campaign and at the DNI's office.
DNI spokesman Richard Willing said the briefings were on "topics of national security interest."
Obama was given the briefing at the FBI field office in Chicago. A team of intelligence experts from the DNI office traveled to Chicago to brief the democratic candidate on national security and intelligence issues, according to sources.
The briefing was more extensive than what he would normally get as a senator on the Foreign Relations Committee, but not as detailed as the daily briefing given to the president.
President Bush has followed the practice of previous presidents in deciding that intelligence briefings will be made available to the presidential and vice presidential candidates of both major parties, CNN has learned.
Sen. Joe Biden, Obama's running mate, has not yet received a briefing. The Republican ticket, Sen. McCain and Gov. Sarah Palin, will be able to be briefed once they are officially nominated later this week.
