Calisher, CSU virologist & lone signatory to completely change his position, told ⁦⁦@ABC⁩ he now believes "there is too much coincidence" to ignore the lab-leak theory & "it is more likely that it came out of that lab."

For more context, Calisher was the unfortunate first author of @TheLancet letter which ordered its signatories alphabetically.

Peter Daszak with ties to the WIV was the drafter of the letter who even considered taking his name off said letter.

Actually another virologist signatory of @TheLancet letter also had a striking change of mind @ABC please update your story! Thanks!

For the sake of transparency, one of the signatories of the @ScienceMagazine letter asking for a credible investigation into both natural and lab origins hypotheses has also reversed position:

The @ScienceMagazine letter is here for reference:
"Theories of accidental release from a lab and zoonotic spillover both remain viable."
"We must take hypotheses about both natural and laboratory spillovers seriously until we have sufficient data."
