Senator Elizabeth Warren is officially running in the 2020 presidential election.

She announced her candidacy Saturday with a speech in Lawrence, Massachusetts, where she told cheering supporters "we need to clean up Washington."

The 69-year-old Democrat said she's in the race to fight for "fundamental change" for all Americans.

She hopes that her call to fight back against a "rigged system" will resonate as she battles at least five fellow senators for the nomination and chance to challenge President Donald Trump in 2020.

Warren has made worker rights, fair wages and access to health care central themes in her campaign. Warren was introduced today by Representative Joe Kennedy III and picked up the endorsement of several other members of the state's congressional delegation.

Warren has spent the past decade in the national spotlight, first emerging as a consumer activist during the financial crisis.
