Biden aides asked whether Senate rules were broken in the wake of the contentious exchange between the vice president and the reporter.

Jason Mattera, who works for Human Events, a conservative magazine, used a pretext to catch Biden off guard in a Senate hallway and grill him on claims the vice president has made about jobs legislation.

Biden’s office has also contacted the standing committee of correspondents, which oversees the gallery, regarding whether Mattera broke the rules by ambushing him…

Mattera admits to using a pretext to momentarily disarm Biden, but argues his methods were justified.

“ABC and CBS have done undercover sting operations and have done them for decades. The fact that a conservative publication goes after a public official who was misrepresenting himself and a Senate bill to the public and tries to get an answer from him, that’s great,” he said in an interview Monday.
