During Rubio's first four years in the U.S. Senate, Republicans were in the minority. After the 2014 midterm elections, the Republicans obtained majority control of the Senate, giving Rubio and the Republicans vast federal influence during the final two years of Barack Obama's presidency, as well as during all four years of Donald Trump's presidency. After the 2020 elections, the Democrats regained majority control of the Senate, and Rubio has reassumed minority status within the Senate.
