NBC News characterized its investigation of “alleged war criminals and terrorists living in the United States and elsewhere” as an independent one.

“Any contact with foreign governments has been consistent with acceptable journalistic practices,” NBC News the news division said in a statement. “Beyond that, it is our policy not to comment on our news gathering.” NBC said the programs are months away from a broadcast date.

Mr. Munyakazi was suspended in December as the college investigated the claims and was arrested last week for overstaying his visa. He will face a deportation hearing in April.

On Dec. 9, an NBC film crew began shooting on the Goucher campus and set up an interview with the college’s president, Sanford J. Ungar, for the next day. At that meeting, Mr. Ungar said he “listened in disbelief” as a Rwandan official shared the details of an indictment calling for Mr. Munyakazi’s arrest.

That same day, the NBC producers showed Kate Pipkin, the director of communications for the college, a short video clip of a person making claims about Mr. Munyakazi’s alleged crimes.

“I think they wanted it to be an ambush, to be frank,” Ms. Pipkin said.

Later that day, the producers approached Mr. Munyakazi in his classroom after students had left. Confronted with cameras and microphones, he rejected the requests for an on-camera interview. “They were hostile toward me,” he said.

The apparent cooperation between NBC and the Rwandan official, Jean Bosco Mutangana, puts the network at odds with many journalism practitioners, including Mr. Ungar, who is a former host of National Public Radio’s “All Things Considered,” who argue that journalists should work independently of any governmental entity.
