WASHINGTON (AP) — Sen. Elizabeth Warren is preparing to bring a populist message to Iowa voters just days after taking her first major step toward launching a campaign for president.

The Massachusetts Democrat told reporters on Wednesday she's planning to visit the state with the nation's first presidential caucuses after being sworn in on Thursday to a second Senate term.

Warren said Washington "works great for the wealthy and the well-connected, it needs to work for everybody else" and vowed to focus on issues like student loans and the cost of getting prescriptions filled.

Warren on Monday announced she's launching an exploratory committee for president.

She's one of what is expected to be a crowded field of Democratic contenders hoping to retake the White House from Republican President Donald Trump in 2020.
