Rubio, who has been involved in bipartisan negotiations on crafting an immigration reform bill, said he had been given the green light to update his Republican colleagues next week.

“Earlier this week, I requested and received permission to brief the entire Republican conference during our policy lunch next week. I look forward to briefing you at that meeting,” Rubio wrote in a letter to four Senate Republicans on Friday.

Rubio’s letter was in response to the four GOP senators, Mike Lee (Utah), Jeff Sessions (Ala.), Chuck Grassley (Iowa), and Ted Cruz (Texas), who urged Rubio and other senators involved in the immigration negotiations to offer more transparency on the bill’s progress.
