VOICED: Lopez Obrador presenta pruebas

Andrés Manuel López Obrador officially challenged the presidential election results in Mexico, claiming the election was unconstitutional due to vote buying. He alleged that the ruling minority orchestrated a massive vote-buying operation to ensure Enrique Peña Nieto's victory. Despite losing by over three million votes, López Obrador presented evidence, including ballots and documents, to support his claims. The PRI, Peña Nieto's party, defended the election's legality and accused López Obrador of being a sore loser.
