The ad, which ran on Friday, was put up as a stunt by a left-leaning Political Action Committee, or PAC, called The Really Online Lefty League, to test Facebooks political ad policies.
The Lead Stories article also explained that due to Facebook policy, any Facebook posts, including ads made by a politician, are not eligible to be rated by the third-party fact-checkers Facebook is working with, like Lead Stories.
Facebook has been criticized in recent weeks over its decision to not fact-check ads run by politicians, drawing ire from Democratic candidates running in the 2020 presidential election such as former Vice President Joe Biden and Senator Elizabeth Warren.
Last week, Facebook Chief Executive Mark Zuckerberg defended Facebooks policy, saying that the company did not want to stifle political speech.
Facebook spokesman Tom Channick told Reuters on Friday that since the new ad came from a political action group, rather than a politician, it was eligible for review by the companys third-party fact-checking partners.
The ad was posted days after Representative Alexandria Ocasio-Cortez grilled Zuckerberg on whether Facebook would permit her to run such an ad, during a congressional hearing on Wednesday.
The Washington Examiner reported that Ocasio-Cortez asked Zuckerberg whether Facebook would allow ads targeting Republicans in primary contests that erroneously said they supported the Green New Deal, to which the Facebook head said probably.
Senator Grahams office said on Friday that it was aware of the ad and confirmed the senator opposes the Green New Deal, a proposal championed by Ocasio-Cortez.
