Rep. Tom Cotton (R., Ark.) announced Tuesday he will challenge Mark Pryor, the senior senator from his state and one of the most vulnerable Democrats up for re-election next year.
Cotton, a former management consultant who served in the Army in Iraq and Afghanistan, was elected in November to represent Arkansas’ 4th Congressional District that stretches across the western and southern parts of the state.
A recent poll shows Cotton with a 43-41 percent lead over Pryor.
