According to Aljazeera:

Venezuela’s VP says Maduro the ‘only president’ of Venezuela

Venezuela’s Vice-President Delcy Rodriguez has given her first public address following the US military operation that captured Maduro and his wife.

“We demand the immediate release of President Nicolas Maduro and his wife. The only president of Venezuela is President Nicolas Maduro,” said Rodriguez.

Rodriguez called for calm and unity to defend ‌the country amid Maduro’s “kidnapping” and said Venezuela will ‍never be the colony of any nation.

This goes against Rubio's claim a few hours ago that Rodriguez would be a US puppet leader.
