Vice President Amissah-Arthur was out of the country on an official duty when the accident occurred.
He, however, made his way to the 37 Military Hospital to find out the state of health of the recuperating journalists after touching down from Kigali, Rwanda.
The accident, which occurred on the Shai Hills stretch of the Afienya-Dawhenya road, left one – Samuel Nuamah of the Ghanaian Times – dead.
The mini-bus in which the 20 journalists were travelling burst a tyre and somersaulted several times before landing in a swamp.
They were returning from an assignment in Ho, where President John Dramani Mahama had joined members of the EP Church Ghana for its annual convention.
President Mahama visited the injured that Thursday night.
Government has promised to take care of the medical bills of the injured journalists.
Vice President Amissah-Arthur was accompanied by Volta Region Minister Helen Adjoa Ntosoo.
