In her speech on Roosevelt Island in New York to thousands of Democratic supporters, the leading candidate Clinton presented her guidelines in the 2016 bid.

She said she runs for the election to become a president of all Americans and pledged to boost equal opportunities and struggle for the middle class who are facing many difficulties.

The former Secretary of State said she would rewrite the US tax code if she is elected so that it rewards hard work, and not quick equities trades or money stashed away overseas.

She also pledged to establish a national infrastructure bank financed by bonds, an idea championed by President Barack Obama, a fellow Democrat.

She declared to turn the US into a clean energy power in the 21st century.
