Nearly a half-dozen Louisiana delegates who previously supported Marco Rubio released a letter on Thursday pledging to back Donald Trump at the convention and calling on the presumptive Republican nominee to choose Rubio as his running mate.

“Previously being undeclared after supporting Sen. Marco Rubio, the five undersigned delegates feel it is important to coalesce around one candidate and begin the process of party unity for the ultimate goal of defeating the Democratic challenger in the fall,” wrote the “Rubio Five.”

The letter, which was obtained by the Washington Examiner, continued, “We firmly believe the process of achieving consensus involves not only supporting the presumptive nominee but also asking him to listen to the will of the other voters who may not have originally supported him.”
