In case it wasn't clear, it is a quote from a Washington Post article, which in turn describes how this (previous) article was edited/corrected:

> In an article published Thursday, economist Jeffrey Sachs called for an independent investigation of information held by U.S.-based institutions that could shed light on the origins of the Covid-19 pandemic. Writing in the Proceedings of the National Academy of Sciences, Sachs and his co-author, Neil Harrison, a Columbia University professor of molecular pharmacology and therapeutics, said that federal agencies and universities possess evidence that has not been adequately reviewed, including virus databases, biological samples, viral sequences, email communications, and laboratory notebooks. Sachs and Harrison also highlighted a tantalizing scientific detail that may be an indication that SARS-CoV-2, the coronavirus that causes Covid-19, originated in a laboratory: a sequence of eight amino acids on a critical part of the virus’s spike protein that is identical to an amino acid sequence found in cells that line human airways [1]

If the Lancet Covid Commission is now claiming it is one of the foremost theories, then it is not fringe.

Looks like they made the edit clear with a correction note, however they have left that undated.
