Kent Alexander, who has traveled the world since 2011 as general counsel of international aid organization CARE Inc., has joined Michelle Nunn’s U.S. Senate campaign as chief of staff and strategy.

Alexander announced his new position in a Dec. 27 letter emailed to friends and colleagues that also solicited contributions for a year-end fundraising deadline in Nunn’s campaign to win the Democratic nomination to replace retiring Republican U.S. Sen. Saxby Chambliss.
