Colombian Senator Iván Cepeda has stated he will not recognize Abelardo de la Espriella as the nation's new president unless de la Espriella renounces his U.S. citizenship. Cepeda, who lost the recent presidential election to de la Espriella, argued on Tuesday that dual citizenship could create conflicts of interest for Colombia's head of state.

Cepeda also called on de la Espriella to clarify whether he acts as an agent of the United States. This concern stems from de la Espriella's past representation of a former paramilitary leader who was an informant for the U.S. Drug Enforcement Administration. Additionally, Cepeda urged de la Espriella to abandon any attempts to extradite outgoing President Gustavo Petro, who is reportedly under investigation by federal prosecutors in Brooklyn for potential ties to drug traffickers.

"If these conditions of legality are not met, as the leader of the opposition, I will embark on the path of peaceful civil disobedience that implies not recognizing the authority of someone who will not defend our national sovereignty," Cepeda said in a statement.

De la Espriella, a conservative lawyer endorsed by former U.S. President Donald Trump, won the presidential runoff on June 21, defeating Cepeda by approximately 250,000 votes. Cepeda initially acknowledged the election results three days later, after Colombian authorities validated the quick vote count showing de la Espriella secured 49.6% of the vote compared to Cepeda's 48.7%.

De la Espriella, who is set to be inaugurated on August 7, was born in Bogota and obtained U.S. citizenship as an adult after living in Florida. His law firm there represented high-profile clients, including individuals accused of human rights abuses and money laundering.

While Cepeda's threat of non-recognition is not expected to have legal ramifications, as de la Espriella has been certified as the winner by the National Electoral Council, it could potentially incite street protests or parliamentary opposition. Cepeda's Historical Pact party holds the largest number of senators in Colombia, though it falls short of a majority needed to unilaterally block legislation.
