The Zimbabwean hunter who led the expedition that killed Cecil the lion has appeared in court.
Theo Bronkhorst, who runs a safari company, will stand trial on September 28 on charges of organising an illegal hunt.
Bronkhorst denies any wrongdoing over the hunt in July, when US dentist Walter Palmer paid to shoot Cecil with a bow and arrow.
On Wednesday he said the case against him was "frivolous" and "wrong".
American philanthropists have pledged to match new donations up to $100,000 to the research team who had been tracking Cecil since 2008.
Dozens of protesters gathered outside the practice of a suburban Minneapolis dentist who killed a protected lion in Zimbabwe.
A host of celebrities have taken to social media to speak out on the killing of well-known lion Cecil in Zimbabwe by a US dentist.
