John McCain (R-Ariz.) to do so.
"Mark Pryor voted the same way as John McCain and many other Republican senators," Pryor's ad fires back. "Secure the border first. Pryor voted no amnesty, 20,000 new border agents, a 700-mile fence and a long-term solution. It's tough but fair. While Congressman Cotton voted to cut funding for border protection and played politics with our security."
With the ongoing humanitarian crisis at the border, immigration has taken on renewed life as a 2014 campaign issue in a number of states.
Pryor and Cotton are locked in a tight race, according to polls.
