Media face hard questions on Trump, Wuhan lab

The media face hard questions amid a growing acceptance that it is possible COVID-19 originated in a Chinese laboratory.

The idea was disparaged as a conspiracy theory by multiple outlets last year - almost surely because its loudest promoter was then-President Trump.

Now, as uncertainty grows, there are burgeoning suspicions that the media overstepped their mark.

For conservatives and some media critics, that's part of the larger issue of bias. 

They argue, for example, that mainstream outlets have played down the severity of the crisis at the southwestern border under President Biden by comparison with the coverage the issue received under Trump.
