(CNN) - Attorney General Eric Holder will begin meetings with representatives of media organizations this week as part of his review of how the federal government handles leak investigations, a Justice Department official said Wednesday.
The meetings with chiefs of Washington bureaus will begin Thursday, and will include representatives from a wide range of media outlets, including newspapers, wire services, radio and television broadcasters, and online organizations.
The official said executives and general counsels of media companies would be included in later discussions along with intelligence experts from within the government. Holder and Deputy Attorney General James Cole will participate in the meetings, the official said.
Last week President Barack Obama said he had asked Holder to conduct a review of how the Justice Department investigates media organizations as part of its greater effort to crack down on leaks of classified national security information. Speaking Thursday, Obama said he was "troubled by the possibility that leak investigations may chill the investigative journalism that holds government accountable."
The review comes amid two revelations about the Justice Department seizing journalists' records in attempts to ferret out leakers of secret information.
Phone records of reporters and editors at the Associated Press were seized in an attempt to determine who leaked information about a failed plot against the United States to the news agency.
And records for a Fox News reporter were tracked, along with the reporter's movements within the State Department, in an investigation into leaks surrounding an intelligence report about North Korea.
Some have questioned whether Holder should be responsible for conducting the review, since he was directly involved in the decision to search the Fox reporter's e-mail records.
"You cannot investigate yourself, and I think it's a total conflict of interest," said Sen. Tom Coburn, R-Oklahoma, on CBS's "Face the Nation" Sunday.
