EXCLUSIVE — Sen. Katie Britt (R-AL) has spent big money behind the scenes for Republican Senate candidates in key races, a move that could raise her standing among GOP colleagues and buoy future ambitions to rise up the leadership rung.

The first-term senator and bipartisan dealmaker is not up for reelection until 2028 but has boosted Republican candidates this cycle through an aligned issue advocacy group with north of $2 million in ads across Senate races in Florida, Maine, Nebraska, Alaska, and Iowa, according to a source familiar with its spending.
