What does the record show about the defense's challenge to NBI Director Matibag's impartiality based on his wife's endorsement of the impeachment complaint?

Defense's bias challenge to NBI chief's testimony

During Day-8 cross-examination, defense counsel Mark Vinluan questioned NBI Director Melvin Matibag over a potential conflict of interest, noting that Matibag's wife, Laguna 1st District Rep. Maria Rene Ann Matibag, was among the endorsers of House Resolution No. 989 seeking the Vice President's impeachment. Matibag confirmed the endorsement and rejected the suggestion that it biased his testimony. Defense spokesperson Michael Poa later said the panel raised the matter to test the witness's credibility and possible bias, leaving its weight to the appreciation of the senator-judges.
