Amidst allegations that Morales rigged the 2019 Bolivian general election, after three weeks of widespread protests organized to dispute the election, and after the head of the country's military called for his resignation, Morales resigned on 10 November 2019. The interim government was heavily protested by Morales' supporters, whose protest against Anez was met with lethal force and accusations of a massacre on indigenous pro-Morales protesters. The heated divide and chain of events started after the official results were announced when the Organization of American States (OAS) as well as some local investigators and analysts had claimed irregularities and fraud, but these findings were quickly heavily disputed. The Center for Economic and Policy Research (CEPR) concluded that "it is very likely that Morales won the required 10 percentage point margin to win in the first round of the election on 20 October 2019." David Rosnick, an economist for CEPR, showed that "a basic coding error" was discovered in the OAS's data, and that explained OAS irreproducible findings as OAS had misused its own data when it ordered the time stamps on the tally sheets alphabetically rather than chronologically. However, OAS stood by its findings arguing that "[...] researchers’ work did not address many of the allegations mentioned in the OAS report, including the accusation that Bolivian officials maintained hidden servers that could have permitted the alteration of results", Additionally, observers from the European Union released a report with similar findings and conclusions as the OAS. But Ethical Hacking, the audit company that was featured predominantly in OAS Report, had investigated the hidden servers and reported that no data had been altered or manipulated but those findings were omitted in OAS final report. The tech security company hired by the TSE (under Morales) to audit the elections, also stated that there were multiple irregularities and violations of procedure and that "our function as an auditor security company is to declare everything that was found, and much of what was found supports the conclusion that the electoral process be declared null and void". The New York Times reported on 7 June 2020, that the OAS analysis immediately after the 20 October election, was flawed yet fuelled “a chain of events that changed the South American nation’s history”.
