Rangel did not however specifically call on the military to switch their allegiance to Guaido, who is recognized as interim president by much of the international community.
The 35-year-old National Assembly speaker, who organized a failed uprising on April 30, has repeatedly called on the armed forces to abandon Maduro.
A source close to Venezuela’s military told AFP that Rangel has not been on active duty “for years,” and at one point was the manager of a Venezuelan state company in Cuba.
The commander of the Air Force, General Pedro Juliac, denounced Rangel as a traitor on Twitter.
Juliac’s tweet carried a photo of Rangel with a cross over it, and the phrase: “Traitor of the people and of the Revolution.”
“Those without morals will never be able to damage the country, let alone the Bolivarian military aviation. We will win – Long Live the Revolution.”
