Earlier Tuesday, Guaido dismissed the high court and Constituent Assembly as illegitimate and continued his calls for Maduro to resign as president.
"They can try to kidnap me," the self-declared president said. "You know how the regime acts. This is not even persecution. This is inquisition."
Step towards prosecution: The Constituent Assembly's decree appears to allow the Supreme Court of Justice to move ahead with a trial of Guaido. But whether Maduro's regime will take action against the 35-year-old lawmaker remains unclear. So far, Maduro has avoided jailing Guaido.
What is the Constituent Assembly? The 545-seat assembly was elected in 2017 to draft a new constitution for Venezuela. Shortly after its first meeting in August 2017, it declared itself the supreme governing body of Venezuela and banned the opposition-led National Assembly.
