This is Johan Giesecke, a former state epidemiologist (Tegnell is the current state epidemiologist), who has been working closely with Tegnell on the epidemic.
He apparently billed Folkhälsomyndigheten (FHM) for some of his interviews, as he thought himself speaking for FHM.
FHM refused to pay after a journalist inquired into it. They said that interviews was not part of Giesecke's responsibilities. He answered that he had discussed the interviews and what he was going to say, with people in FHM, and therefore considered them part of his consultancy contract.

The situation is a mess, and it feels as though many people are trying to muddle the waters, by spreading confusion.
