Morera, who entered the United States as a lawful permanent resident in 2023, is now in the custody of US Immigration and Customs Enforcement pending removal proceedings, according to a statement from ICE.
Morera's presence poses a threat to the United States and undermines American foreign policy interests, the statement said.
In a social media post, Rubio said he revoked Morera's green card because she "was managing real estate assets and living in Florida, while also aiding Havana's communist regime."
Cuba's leadership rarely talks publicly about GAESA, which stands for Grupo de Administración Empresarial - or 'business administration group.'
It has long held that such discretion is necessary to confront a US trade and financial blockade that severely complicates the island's business with the outside world.
Reuters was not immediately able to reach out to representatives of Morera for comment.
Earlier, Rubio told reporters that diplomacy "remains our preference with Cuba", but added: "I'm just being honest with you, you know, the likelihood of that happening, given who we're dealing with right now, is not high."
He also accused Cuba of being "one of the leading sponsors of terrorism in the entire region", which Foreign Minister Bruno Rodríguez vehemently denied in a post on X.
Meanwhile President Donald Trump said past US presidents have mulled intervening in Cuba for decades, but "it looks like I'll be the one that does it."
He'd suggested the opposite a day earlier, however, saying further escalation isn't necessary after US prosecutors announced criminal charges against former Cuban president Raúl Castro in the 1996 downing of civilian planes flown by Miami-based exiles.
