Rep. Tom Cotton (R-Ark.) plans to announce next Tuesday that he will run for the Senate in 2014, according to a report from the Associated Press, giving Republicans a top recruit for a race they are eager to contest.

Cotton is a first-term congressman and Iraq War veteran. He enjoys support in both the conservative and establishment wings of the GOP.

Cotton's spokeswoman would not confirm or deny the AP report. She only said he would speak about his "fight" to represent Arkansas on Tuesday.

"On Tuesday Tom is inviting his hometown and all who have supported him along the way to hear about his fight to represent Arkansas's values in D.C.," said Cotton spokeswoman Caroline Rabbitt. "He looks forward to sharing his plans to continue that fight in the coming year."

The congressman did not respond to an e-mail sent to his personal account asking whether he is running for the Senate.

If he gets through the primary, Cotton would face Sen. Mark Pryor (D), who is shaping up as 2014's most vulnerable Democratic Senate incumbent. The Fix recently rated Arkansas as the the third most likely state to flip in 2014. The two states ahead of it on the list feature open races.
