Alex Berenson has been a great source from very early on. He's suffered greatly for questioning the mainstream COVID narrative. He recently settled a suit with Twitter where they reinstated his account. He has a pretty reasonable perspective and is extremely suspicious of the pharmaceutical industry, which he used to report on for the NYT. Berenson probably considered himself a dyed in the wool classic liberal intellectual before being ostracized by the class. He's been right about much of this and has thoroughly supported his positions.
