The election of former President Donald Trump on Tuesday is looming large over another important race that will unfold next week: who will lead Republicans’ new Senate majority.

The three candidates to become the next GOP leader — Minority Whip John Thune (R-SD), Sen. John Cornyn (R-TX), and Sen. Rick Scott (R-FL) — are preparing for the distinct possibility that Trump could attempt to influence the process by endorsing his favored Republican in the race.
