ST. PAUL, Minn. — Minnesota Gov. Tim Walz, Democrats’ 2024 candidate for vice president, is ending his bid for a third term as governor amid President Donald Trump’s relentless focus on a fraud investigation into child care programs in the state.

Less than four months after announcing his re-election campaign, Walz said Monday that he could no longer devote the energy necessary to win another term, even as he expressed confidence that he could win.

Walz said in a statement Monday that he “can’t give a political campaign my all” after what he described as an “extraordinarily difficult year for our state.”

“Donald Trump and his allies – in Washington, in St. Paul, and online – want to make our state a colder, meaner place,” Walz said, referring to the Trump administration withholding funds for the programs. “They want to poison our people against each other by attacking our neighbors. And, ultimately, they want to take away much of what makes Minnesota the best place in America to raise a family.”

Democratic Sen. Amy Klobuchar of Minnesota is considering running for governor, according to a person close to her. The person, who wasn’t authorized to speak publicly and spoke on the condition of anonymity, said Klobuchar has not made a final decision.

Around a dozen Republicans are already in the race. They include MyPillow founder and chief executive Mike Lindell, an election denier who is close to Trump. They also include Minnesota House Speaker Lisa Demuth, of Cold Spring; Dr. Scott Jensen, a former state senator from Chaska who was the party’s 2022 candidate; state Rep. Kristin Robbins, of Maple Grove; defense lawyer and former federal prosecutor Chris Madel; former executive Kendall Qualls; and former Minnesota GOP Chair David Hann.

Walz is a military veteran and union supporter who helped enact an ambitious Democratic agenda for his state, including sweeping protections for abortion rights and generous aid to families.

Vice President Kamala Harris picked Walz as her running mate after his attack line against Trump and his running mate, then-Ohio Sen. J.D. Vance — “These guys are just weird” — spread widely.

Walz had been building up his national profile since his and Harris’ defeat in November. He was a sharp critic of Trump as he toured early caucus and primary states. In May, he called on Democrats in South Carolina to stand up to the Republican president, saying, “Maybe it’s time for us to be a little meaner.”

Through two terms as governor, Walz has moved a liberal agenda through a closely divided legislature. In his first term, he navigated a Democratic-led House and a Republican-controlled Senate that resisted his proposals to use higher taxes to boost money for schools, health care and roads. But he helped broker compromises.

He used the office’s emergency power during the COVID-19 pandemic to shutter businesses and close schools, prompting Republican pushback.

Republicans also were critical of Walz over what they saw as his slow response to sometimes violent unrest that followed the killing of George Floyd by a Minneapolis police officer in 2020.

In his second term, Walz worked with Democratic majorities in both legislative chambers to chart a more liberal course in state government, aided by a huge budget surplus. Minnesota eliminated nearly all of the state abortion restrictions enacted in the past by Republicans, protected gender-affirming care for transgender youth and legalized the recreational use of marijuana.

That, combined with Walz’s rural background and experience representing southern Minnesota in Congress, landed him on Harris’ radar as she considered potential running mates in her 2024 presidential bid. After a whirlwind search, she opted for Walz over other candidates including North Carolina’s Roy Cooper, Kentucky’s Andy Beshear, Pennsylvania’s Josh Shapiro and former Transportation Secretary Pete Buttigieg.

Walz got a warm welcome from Democratic voters but drew mixed reviews for his lone debate against his Vance.

Minnesota has leaned Democratic in presidential and statewide contests in recent decades. Walz won his second term in 2022 by nearly 8 percentage points, but Trump narrowed Democrats’ advantage to less than 5 points in 2024.
