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.

On Thursday in Ohio, John BoehnerJohn BoehnerIt's time for McConnell to fight with Trump instead of against him How Republicans can bring order out of the GOP's chaos Republican donor sues GOP for fraud over ObamaCare repeal failure MORE poked fun at Republicans who do not want to move forward on immigration reform, saying they have chosen the path of least resistance.

"Here's the attitude. 'Ohhhh. Don't make me do this. Ohhhh. This is too hard,' " Boehner said in a mocking voice. 

House leaders outlined a set of immigration principles earlier this year that planned a path to legalization for immigrants living in the country illegally. However, leaders have opposed taking up the comprehensive Senate bill and have argued for a more piecemeal approach.
