Dennis Muilenburg, the chief executive of Boeing, was allowed to listen in as then President-elect Donald Trump made a telephone call about the F-35 jet project being run by rival Lockheed Martin, Bloomberg reported.
Lockheed has a heavy Colorado presence, but much of the fighter jet's production is in Fort Worth, Texas.
The call in question was to Chris Bogdan, the U.S. Air Force lieutenant general in charge of the project. Bogdan said only "publicly releasable" information was discussed, according to Bloomberg.
Lockheed declined to comment to Bloomberg.
