The current presidency has been disputed between Juan Guaido and Nicolás Maduro since January 10, 2019, in the ongoing Venezuelan presidential crisis. Maduro was elected to his first term in 2013 but received backlash from opposing Venezuelans and some members of the international community especially the United States. Maduro was accused of authoritarian rule and fraud in the elections that were held on May 20, 2018. Guaido, the President of the National Assembly of Venezuela, took the Oath of Office as Interim President on January 23, 2019, citing Article 233 of the Constitution of Venezuela to "cease the usurpation, hold a transitional government, and call for new elections". The office remains disputed.
