FRANKFORT, Ky. (AP) — Kentucky's bitter U.S. Senate race turned more combative Friday, with both state parties filing dueling complaints against Republican Sen. Mitch McConnell and Democratic challenger Alison Lundergan Grimes.
The first salvo came from the state Republican Party, which submitted a complaint to the Federal Election Commission alleging Grimes accepted prohibited campaign donations from her father's company.
The state Democratic Party followed with its complaint asking the Senate Ethics Committee to investigate whether McConnell improperly solicited campaign contributions in the U.S. Capitol.
The complaints ratcheted up an already-contentious race, one of the nation's most closely watched.
McConnell, the top-ranking Senate Republican, is seeking a sixth term. He is facing his toughest re-election race against Grimes, who is Kentucky's secretary of state.
Both campaigns were quick to denounce the complaints aimed at them.
