WASHINGTON, D.C. (AP) – Sen. Mike Rounds announced he is seeking reelection after a period of uncertainty as his wife underwent cancer treatment in recent months. The first-term Republican from South Dakota made the announcement the day after voting to acquit President Donald Trump of impeachment charges.

He will face a state representative in the Republican primary. South Dakota Rep. Scyller Borglum is running against Rounds and has tried to position herself as more right-wing than Rounds, who holds a huge cash advantage over Borglum.
