Hillary Rodham Clinton says she's running for president.  The former first lady and secretary of state made her 2016 plans official on her campaign website Sunday.

She says in a video that "everyday Americans need a champion.  I want to be that champion."  Clinton is aiming to be the first female president.

Clinton enters the Democratic primaries in a strong position to succeed her 2008 rival, President Barack Obama.

Following Sunday's announcement, she's expected to travel soon to early voting states, including Iowa and New Hampshire.
