Senate Majority Leader John Thune (R-SD) has chosen four informal advisers to add to his leadership team, a list that includes his former rival for GOP leader: Sen. John Cornyn (R-TX).

Cornyn and three others — Sens. Steve Daines (R-MT), Markwayne Mullin (R-OK), and Marsha Blackburn (R-TN) — will attend Thune’s weekly leadership meetings, according to an aide, as he settles into the position long held by Senate GOP Leader Mitch McConnell (R-KY).
