Condoleezza Rice is best known for her role as security advisor and secretary of state under the George W. Bush administration.
But her journey to politics -- and the Republican Party -- is one of inspiration.
In her latest book, No Higher Honor, Rice talks about her years in Washington and the foreign policy decisions she helped make, some she admits in hindsight weren't the best.
Kristi Watts, co-host of "The 700 Club," recently sat down with Condoleezza Rice to discuss the memoir and her life in politics.
Rice said she realized early on her interest stood in foreign policy and the decisions coming from U.S. leaders.
"I went through a long journey towards being a Republican. I actually registered as a Democrat when I first could vote in 1976," Rice said.
"But I was very disturbed by the Soviet onslaught when the Soviet union invaded Afghanistan. I thought, 'We need somebody who understands power.' And I voted for Ronald Reagan," she continued.
"So it was foreign policy initially that brought me to the (Republican) party," Rice explained.

Rice grew up in the segregated South and her father was a Presbyterian minister.
That environment helped shape beliefs she said came in handy while dealing with secret intel in Washington.
"It was pretty scary. But several things get you through. First of all faith," Rice said, explaining what it felt like to govern elements key to America's national security.
"It was good to be around other people who had the same faith," she added. "President Bush is a person of faith, and it helped working with people like that."
Today, Rice said one of her greatest foreign policy concerns is with Iran.
"I worry about Iran. It's probably the most dangerous single country in the world," she told Watts. "They've got tentacles of terrorism all over the world and they're seeking a nuclear weapon."
Rice said if Iran reaches its nuclear weapon goal, it would bring "unimaginable danger."
Because of realities like this, Rice said we should pray against "harm and hurt" around the world, "for the compassion of our nation," and "for our leaders that they will have wisdom."
