The outgoing United States ambassador to Nigeria, James Entwistle, was not available on Thursday to provide video evidence of the alleged sexual misconduct against three members of the Federal House of Representatives.
Entwistle, who failed to show up at the investigative hearing by the National Assembly joint committees on ethics and privileges, and foreign affairs, was meant to provide evidence against the accused lawmakers.
The three lawmakers accused of sexual misconduct are Mohammed Gololo, Samuel Ikon and Mark Gbillah.
Chairman of the joint committees, Ossai Ossai, explained that the Minister of Foreign Affairs, Geoffrey Onyeama, and Entwistle were meant to appear together at the hearing.
Onyeama wrote a letter to the committee to plead that he was away for an African Union summit holding in Kigali, Rwanda.
He asked the committee to put the hearing at a later date, and promised to appear.
Ossai further expressed optimism that Onyeama and Entwistle would show up on July 20, the new date of the hearing, to give their own accounts regarding the sexual misconduct allegation leveled against the lawmakers.
Also speaking, the Chairman, House Committee on Foreign Affairs, Nnenna Ukeji, said the diplomatic angle to the matter would be handled according to the Vienna convention of 1961.
She also said the committee would seek guidance of the foreign affairs ministry where necessary.
This will be the second time that the committee will postpone the hearing.
