Patently untrue. This year alone there was active reporting on Assange from up to June on most popular US media outlets which suddenly stopped. My comment from an earlier thread on July 3rd:

There have been 20 articles in print and on the web mentioning Assange in the NY Times since 2021 began, avidly covering the details of his trial and extradition, but now nothing. If their search features are any indication, CNN doesn't believe you should seek out news as much as passively accept it-same pattern and then no recent mention.

Reuters' latest article from 25 June in a break from the style of their previous coverage leaves out mention of the trial details entirely in favor of a human element story petitioning Biden free Assange "to show the US has changed". This narrative does little to exculpate Assange or share why the trial may be over for good while preempting any credit for what follows to the mercy and wisdom of Biden. Whether Biden ignores or denies, well, them's the laws, you know.
