Two sources close to the Clinton campaign say former Secretary of State Hillary Clinton will announce her candidacy for president of the United States "as early as Sunday."
She is expected to make the announcement on social media, with campaign stops planned for next week, including to first-in-the-nation caucus state Iowa.
Clinton, who ran unsuccessfully for the Democratic nomination in 2008, now enters the race as the undisputed frontrunner for her party's nod. Only a handful of other Democrats have expressed interest in pursuing a White House bid, including former Maryland Gov. Martin O'Malley, former Virginia Sen. Jim Webb and independent Sen. Bernie Sanders of Vermont. But none have Clinton's broad name recognition, massive fundraising apparatus and sky-high approval ratings within the party.
