Facebook said in a statement on Thursday night that some political ads were “improperly” restricted due to a technical error.
The company explained in a blog post that the glitch was a result of their initiative to block any new political ads in the week prior to the 2020 presidential election.
After the restriction went into effect, Facebook said “technical flaws” caused a number of ads “to be paused improperly.”
The social media giant insured that they had “implemented changes to fix these issues” and most of the advertisements had been running without any issues.
Earlier in the day, Democrat Joe Biden’s presidential campaign had expressed outrage about the ad glitch. A rep for the campaign told Business Insider that the bug impacted their voter turnout operation and cost them about $500,000 in fundraising.
“We have no sense of the scale of the problem, who it is affecting, and their plan to resolve it,” Rob Flaherty, the Biden campaign’s digital director, told the outlet.
“We find ourselves 5 days out from Election Day unable to trust that our ads will run properly, or if our opponents are being given an unfair, partisan advantage.”
It was not immediately clear if any content from President Trump’s campaign had been affected by the glitch.
