Republican U.S. Rep. Tom Cotton's campaign says he's raised $2.28 million over the last three months in his bid to unseat Democratic U.S. Sen. Mark Pryor, outpacing the incumbent lawmaker in their increasingly heated and expensive Senate race.
Cotton's campaign announced Monday he raised the money during the fundraising period that ended June 30. Pryor's campaign on Friday announced he had raised $1.5 million during the same period.
Pryor was first elected in 2002 and is the only Democratic member of the state's congressional delegation. Cotton was elected in 2012 to represent south Arkansas' 4th Congressional District.
The race is one of the most closely watched in the country, with outside groups spending millions on television ads that have been blanketing the state.
