Senate Republicans' main super PAC is pouring tens of millions into Kansas and cutting back in North Carolina as the fight for the Senate majority turns more defensive.

Punchbowl News reported Monday that the Senate Leadership Fund plans to invest $14 million in television and digital ads to defend GOP Sen. Roger Marshall in Kansas. The state has become competitive even though President Donald Trump won it by about 16 points in 2024. Marshall faces Democrat Adam Hamilton, a Methodist pastor who leads the nation's largest United Methodist church. A Democrat has not won a Kansas Senate seat since 1932.

CBS News reported Friday that the group had reserved about $9.8 million in Kansas ads, according to AdImpact, and paused future North Carolina spending after already putting more than $30 million into that race. An AP story carried by Scripps News put the earlier Kansas reservation near $8.2 million and said the group had planned about $18 million more in North Carolina over the next month before the pullback.

Punchbowl also listed other defensive buys, including more money in Maine, Alaska, Michigan, Iowa and Ohio. NRSC Chair Sen. Tim Scott has said Kansas is more competitive than he would like. Hamilton's campaign called the spending a sign that Republicans are panicking over Marshall's record. Marshall's campaign did not immediately answer CBS News.

What we know: The Senate Leadership Fund is shifting cash into Kansas and away from North Carolina.
What we don't: Whether the late ad flood changes either race before Nov. 3.
