US Attorney General William Barr gave blanket authorization on Monday for federal prosecutors to open investigations into alleged voting irregularities in the US presidential election. The AFP reports that Barr reversed federal policy and unleashed prosecutors from pursuing election fraud before all votes were officially tallied. Barr said in a letter to US attorneys around the country “Given that voting in our current elections has now concluded, I authorize you to pursue substantial allegations of voting and vote tabulation irregularities prior to the certification of elections in your jurisdictions in certain cases,” US President Donald Trump has refused to concede defeat in the elections, despite Democratic challenger Joe Biden being roundly declared the clear victor.
