ORLANDO, Florida (CNN) - Vice President Dick Cheney's daughter Elizabeth Cheney is joining Mitt Romney's presidential bid, his campaign announced Sunday.
She previously stumped for former Sen. Fred Thompson of Tennessee who dropped out of the race last week.
In a statement released by Romney's campaign, Cheney said the former Massachusetts governor "has distinguished himself as a leader who can guide our country with a clear vision for overcoming the threats we face today."
She also called him "the only candidate who has outlined a comprehensive strategy for defeating the global Jihadist threat."
Cheney, 41, once served as the principal deputy assistant secretary for Near Eastern Affairs at the State Department. She stepped down from the senior-level post in 2006.
She also worked in the State Department from 2002 to 2003, before leaving to work on her father's re-election campaign.
