Vice President Kamala Harris has chosen Minnesota Gov. Tim Walz as her running mate, looking to strengthen the Democratic ticket in Midwestern states.

She will introduce Walz at a rally Tuesday evening in Philadelphia.

U.S. Sen. Amy Klobuchar says Walz is someone who is “just unendingly optimistic and joyous, and that is very, very important right now in our politics.”

The fellow Minnesotan who served with Walz in Congress told The Associated Press “he’s blunt, but he’s also positive” in a way she believes will provide an upbeat message in contrast to the Trump-Vance Republican ticket.

“I always think of him in his plaid shirt because he was always making the point it’s ‘One Minnesota,’” said Klobuchar, a Democrat. “And I think that’s a point you’re going hear him talk about with our nation.”

She said his background as a hunter and someone who fishes “just brings a different perspective to the White House.”
