Flake, a member of the "Gang of Eight" in the Senate, helped steer a comprehensive immigration reform proposal to passage in the upper chamber last year. And he has been increasingly vocal in pushing for immigration reform on social media in the past week.

On Tuesday, Flake applauded former Florida Gov. Jeb Bush (R) for "having the guts" to say that some illegal border crossings are an "act of love” and said he agreed with the former governor.
