When Trump himself floated the lab-leak hypothesis last April, his divisiveness and lack of credibility made things more, not less, challenging for those seeking the truth.
Right, it's Trump's fault that the media and political opposition acted like children in opposing every word that came out of his mouth.
Apply that logic to your favorite left-leaning politician:
"The fact that Obama was always a natural born citizen would have been accepted by some Conservatives who thought he was born in Kenya, but the fact that Obama denied the claims that he was foreign-born made things worse."
When you're wrong, you're wrong. Try to own up to it without blaming the people who were actually right.
