The US government broadcaster is the Voice of America. For a long time it was unavailable to Americans (propaganda laws), but is now. Some Europeans may be familiar with Radio Free Europe/Radio Liberty, that is also US-funded by the same agency as the Voice of America.
We also have NPR and public broadcasting (PBS), both have news. They receive government funding through the Corporation for Public Broadcasting, which is supposed to be objective although there have been issues in recent history. They also have corporate donors, which could affect objectivity.
