Clinton to announce presidential bid on Sunday

WASHINGTON - Hillary Clinton is expected on Sunday to announce, via video and social media, her intention to seek the Democratic presidential nomination, a party official told Reuters on Friday.

Following the announcement, the former secretary of state will travel to the key primary states of Iowa and New Hampshire, said the source, who is close to Clinton.

"She's expected to make her intention to run known on Sunday," the source said.

In her previous presidential run in 2008, Clinton lost to the current president, Barack Obama, in part because of the Obama campaign's clever use of social media to draw attention to his candidacy and raise huge sums through small donations.

Her use of social media is also an appeal to young voters, whom Clinton needs to become American's first woman president.

In 2012, young political staffers made the now 67-year-old former first lady an Internet sensation with the blog "Texts from Hillary."

Also on Friday, Clinton released an update to her memoir, "Hard Choices," in which she described her final days as secretary of state and her feelings about her first grandchild, as her campaign is expected to concentrate on making her relatable to ordinary Americans.

"Becoming a grandmother has made me think deeply about the responsibility we all share as stewards of the world we inherit and will one day pass on.

"Rather than make me want to slow down, it has spurred me to speed up," she wrote.
