in my opinion, the objective person would likely agree that Trump and his campaign have been rigorously examined both formally (by Mueller and his team) and informally (by the media).

i don't intend to change topics here, but in context of your usage of "never rigorously examined" one could point to Hunter Biden's international dealings as lacking rigorous examination, as stories on this topic have even been actively suppressed.
