Clinton made it official, declaring the launch of her 2016 presidential campaign via email announcements sent by her campaign chairman John Podesta and by Twitter, Sputniknews reported.
The former secretary of state is considered the frontrunner within the Democratic Party and is the first Democratic presidential candidate to officially announce her bid for the White House in the 2016 presidential election.
Many called Clinton's second attempt at running for president has been the worst-kept secret of the political world, with months of rumors and speculation preceding the announcement.
However, Clinton herself has been low-key, readying for the long run.
Some have criticized Clinton for waiting so long to declare which they say has hurt a Democratic bid. However, the only other 2016 candidate to announce is Ted Cruz, a Republican senator from Texas. Several other prominent Republicans are expected to enter the fray but Clinton's announcement will likely stop most other Democratic potentials from running.
While Clinton is seen as given Democratic nominee next year, Clinton was the favorite to win the 2008 nomination of her party before little-known, then-Senator Barack Obama made his surprise announcement.
Even if Clinton does become the Democratic nominee, Republicans have been laying the groundwork for attacks against her on a number of fronts, particularly related to her record as Secretary of State. Opposition has already been hammering Clinton on the 2012 incident in Benghazi in which a US ambassador was killed and her use of a private email server to conduct official State business.
