LITTLE ROCK, Ark. (AP) - Two national conservative groups say they're prepared to back Republican Rep. Tom Cotton's bid to unseat Democratic Sen. Mark Pryor in Arkansas next year.
The Club for Growth's political action committee on Wednesday endorsed Cotton, while the Senate Conservatives Fund said it's open to supporting the first-term congressman's Senate bid. Cotton announced Tuesday he was running against Pryor.
The Club for Growth also announced that it planned to air a new television ad criticizing Pryor starting Thursday.
Pryor is seeking a third term and is widely viewed by the GOP as the most vulnerable Senate incumbent on the ballot in 2014. Cotton is the first Republican to announce he was running for Pryor's seat.
Both groups aired television ads criticizing Pryor before Cotton joined the race.Copyright 2013 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
