journalists having political preferences may shade their reporting, but it's a stretch to suggest that it causes them to act in conspiracy to exaggerate the impact of Covid or to make up stories about Russian troll farms impacting the election.
In fact, Covid vaccines were important, are still important, and Covid is not a cold or a flu; and Russian influence on politics did happen, is happening, and will happen. All of these things are extensively documented with facts and evidence. That they are now also partisan warfare topics is not a reporting problem but a right wing media and leadership problem.
