Biden’s code name will be “Celtic,” CNN reported, citing two unidentified sources. It’s the same code name Biden had when he served as vice president.

Biden’s national press secretary, TJ Ducklo, said the campaign does not comment on security measures.

The Secret Service protection follows a high-profile protest earlier this month at Biden’s rally in Los Angeles on Super Tuesday. Two animal rights protesters stormed the stage.

The activists previously told The Hill that the security wasn’t tight and there was “easy access to get to” Biden.

At the time, a spokesperson for the Department of Homeland Security (DHS) said the department had not received a recommendation from Congress to provide Secret Service protection for any presidential candidate.

Biden’s campaign submitted its formal request for Secret Service protection last week, a congressional official told CNN.
