Kentucky Secretary of State Alison Lundergan Grimes will speak to the Democratic National Convention in Philadelphia next week.
Grimes was one of dozens of speakers added to the agenda on Thursday. The secretary of state is in her second term in office, having narrowly won re-election in November.
Grimes gained national prominence in 2014 for her challenge to veteran U.S. Sen. Mitch McConnell. McConnell won the race and would go on to become Senate majority leader.
Presumptive Democratic presidential nominee Hillary Clinton campaigned for Grimes several times in her Senate campaign. The Clinton family is close with Grimes and her family, including Jerry Lundergan, Grimes' father and former chairman of the Kentucky Democratic Party.
Grimes' mother, Charlotte Lundergan, is a superdelegate pledged to support Clinton.
