Marco Rubio says he has no plans to endorse Donald Trump or become his vice president.

“I have never sought, will not seek and do not want to be considered for Vice President,” Rubio said.

This is the first time Rubio has explicitly denied speculaiton that he could be in the running for a position in Trump's presidency, should the presumptive Republican nominee win the general election come November. Rubio also said that he'd retain his focuse on his work in the senate, to help Republicans get elected across the ballot in Florida as well as the rest of the states.

"I will focus my attention on representing the people of Florida, retaining a conservative majority in the Senate and electing principled conservatives across the country."
