A situation in which you've (a) contributed to decision-making on multiple public funding priorities including this lab and (b) state a judgment that lab was not the source of the outbreak isn't a conflict of interest, it's everyday policy life. Especially given that there's nothing glaringly wrong with the reasoning Fauci gave for that judgment in the article you linked.
If you think that reasoning has shortcomings, by all means, feel free to actually come up with something resembling a counterargument instead of vaguely implying "whether or not anything shady was going on."
