Florida senator Marco Rubio formally endorsed Donald Trump's 2024 presidential campaign on Sunday, effectively snubbing his state's own governor Ron DeSantis.

In a social media post, Rubio cited his work with Trump to expand child tax credit as well as sanctions placed on Cuba and Venezuela as reasons for throwing his support behind the former president. Rubio added:

I support Trump because that kind of leadership is the ONLY way we will get the extraordinary actions needed to fix the disaster Biden has created.
