Minnesota senator Amy Klobuchar has become the latest Democrat to bid to take on Donald Trump in the 2020 presidential election.
Ms Klobuchar positioned herself as the most prominent Midwestern candidate as her party tries to win back voters in a region that helped put Mr Trump in the White House.
She is the latest to launch her bid in an increasingly crowded field of Democrats vying to challenge Mr Trump.
The current frontrunners for the Democrat nomination, according to bookmakers, include California senator Kamala Harris, former Texas congressman Beto O’Rourke and former US vice president Joe Biden.
Mr O’Rourke and Mr Biden have not yet announced whether they will run in 2020, although Mr O’Rourke said he would make a decision this month.

Announcing her candidature, Ms Klobuchar told an audience on Sunday: “For every American, I’m running for you.
“And I promise you this: As your president, I will look you in the eye. I will tell you what I think. I will focus on getting things done.
“That’s what I’ve done my whole life. And no matter what, I’ll lead from the heart.”
Ms Klobuchar’s announcement comes a day after Elizabeth Warren, a Massachusetts senator, announced she would run for the presidency and makes her the ninth Democrat to launch their White House campaign.
