Washington (CNN) - In the wake of an unscripted and confrontational interview with a reporter from a conservative news organization last week, staff for Vice President Biden phoned a Senate official to raise concerns about the reporter's conduct and to inquire whether the reporter violated any rules governing news coverage on Capitol Hill, a person familiar with the incident told CNN.
In the interview, which took place in a crowded public hallway in the Russell Senate Office Building, Human Events reporter Jason Mattera pointedly questioned Biden about his assertion that rape and other crimes would rise if Congressional Republicans voted down part of the president's jobs bill aimed at funding police jobs.
At issue is whether Mattera was able to position himself close to Biden for the interview by misrepresenting himself.
In video of the incident, Mattera can be seen signaling to Biden that he wants a photo with him, as if he was a member of the public who wanted a souvenir. Only after Biden turned shoulder to shoulder with Mattera, ostensibly to pose for a photo, did the reporter question the Vice President.
In the interview, Biden turned testy. At one point, he warned Mattera not to take his crime rate comments out of context.
"Don't screw around with me," Biden said. "Let's get it straight."
Mattera, who has conducted other so-called "ambush" interviews, was wearing a congressional press credential at the time of the interview with Biden.
Heather Rothman, a BNA reporter, who is the chair of the Executive Committee of Periodical Correspondents, which credentialed Mattera, said her organization is aware of the concerns of the Vice President's office.
"We're aware of the concerns," Rothman said. "We're aware this occurred and the Vice President's office has made contact."
A spokeswoman for Biden declined to comment about the matter.
A CNN review of the rules governing reporters credentialed through the periodical gallery, which are available on its public website, don't point to any obvious infraction by Mattera.
A formal investigation by the Executive Committee of Periodical Correspondents would only take place if the organization received a formal compliant about the reporter's conduct, said the source who confirmed the Vice President's office had called with questions and concerns. To this point, no formal complaint has been filed, the source said.
