Sen. Amy Klobuchar (D-Minn.) says she had a perfectly legitimate reason to stand up for frozen pizzas in school cafeterias, but still regrets taking a stand on the issue.

While answering questions during a CNN town hall in New Hampshire on Monday, the 2020 Democratic presidential candidate was asked about a 2010 letter she sent to the USDA, complaining about a new rule that would no longer count tomato sauce on frozen pizzas served in school cafeterias as a vegetable.

Klobuchar said she wasn't defending the pizzas, but rather farmers and businesses in Minnesota. "We were in the middle of the downturn, and it was a little more, I would say, complex in terms of the language," she said, adding that this was "fair criticism." In 2014, Klobuchar told The New York Times it was a mistake to send the letter, and she told the town hall audience she still regrets mailing it. The bigger issue, she added, is nutrition, and the "need to have healthier foods in kids' lunches." Catherine Garcia

South Bend Mayor Pete Buttigieg, a 2020 Democratic presidential candidate, gave a lengthy interview for ABC's This Week which aired on Sunday. While Buttigieg is usually known for his measured opinions, the 37-year-old mayor was a little more fiery during his conversation with Martha Raddatz. Here are three standout moments.

On the military — Buttigieg, who served in Afghanistan, was highly critical of President Trump's ideas about the military. First, he doubled down on his comments that Trump faked his bone spurs to avoid serving in Vietnam, calling it "an assault on the honor of this country." He later added that Trump's potential pardoning of soldiers accused of war crimes "undermines the foundations of this country."

North Korea negotiations aren't working — While Buttigieg is a fan of diplomacy, he doesn't fully agree with Trump's tactics regarding North Korea. In fact, he thinks the main thing Trump accomplished was legitimizing a rogue state.

His experience comes from his office, not his age — Buttigieg often gets questioned about his youth and lack of experience in Washington. But he argues that his job as mayor might prepare him even more for the presidency than serving in Congress would. "You can be a very senior member of Congress and have never in your life managed more than 100 people," he said. Tim O'Donnell

Bart Starr, a Hall of Fame quarterback known for guiding the Green Bay Packers to victory in the first two Super Bowls ever in 1967 and 1968, died on Sunday in Birmingham, Alabama. Starr had battled numerous health issues in recent years, including two strokes, a heart attack, and several seizures. He was 85.

Starr and the Packers won three other NFL championships before the Super Bowl began, giving him five titles in a decade — a feat not even Tom Brady can claim. Starr also won the league's Most Valuable Player award in 1966.

In a team press release, the Packers described Starr as "maybe the most popular player" in franchise history. He is also known for his game-winning quarterback sneak to beat the Dallas Cowboys in the 1967 NFL championship, a memorable game dubbed the "Ice Bowl" due to the frigid winter temperatures in Green Bay.

"While he may always be best known for his success as the Packers quarterback for 16 years, his true legacy will always be the respectful manner in which he treated every person he met, his humble demeanor, and his generous spirit," his family said in a statement. Tim O'Donnell

Sumo wrestling and trade negotiations make for an unlikely combination. But Japan's Prime Minister Shinzo Abe is hoping the two mesh well.

During his visit to Japan on Sunday, President Trump presented a special "President's Cup" trophy to the winner of a sumo wrestling tournament, one of Japan's most significant cultural institutions. The winner, Asanoyama, became the first recipient of a winner's trophy awarded by a United States president.

Trump and first lady Melania Trump sat in ringside armchairs during the bouts, The Guardian reports, as opposed to the traditional form of viewership — sitting cross-legged on thin cushions.

The gesture, orchestrated by Abe, is widely viewed as a diplomatic attempt to flatter Trump as the two countries gear up for trade negotiations, which Trump tweeted would likely develop more fully after Japan's elections in July.

In the short term, at least, it appears Abe made the right call — Trump seems to have enjoyed the moment. Tim O'Donnell

Felix Klein, Germany's anti-Semitism commissioner, on Saturday warned the country's Jewish population about the potential dangers of donning the kippa, a traditional Jewish skullcap, in public.

Klein said his position on the matter has changed over time, citing a rise in anti-Semitic activity in Germany, mostly on the far right of the political spectrum, including from leaders of the Alternative for Germany Party who have openly questioned Germany's policy of atonement for the Holocaust and other World War II atrocities, France 24 reports. "The internet and social media have largely contributed to this," he said in an interview published by the Funke regional press group. "But so have constant attacks against our culture of remembrance."

Official figures show there were 1,646 hate crimes committed against Jews in Germany in 2018, a sharp increase from the year prior. Klein also suggested police, teachers, and lawyers should receive better training to recognize anti-Semitic behavior.

Recently, Berlin's top legal expert on anti-Semitism, Claudia Vanoni, told Agence France-Presse that while the issue has always been "deeply rooted" in German society, "it has become louder, more aggressive, and flagrant." Tim O'Donnell

President Trump's appeal against an order from a federal judge which allowed for Deutsche Bank and Capital One to hand over financial records to Democratic lawmakers was successful in delaying the process, a Southern District of New York court filing revealed on Saturday.

Until a final decision is reached on the appeal, the two banks will not have to immediately comply with the subpoenas, which call for financial records of Trump, three of his children, and the Trump Organization. The delay is the result of what Reuters calls a "rare accord" between Trump's attorneys, the banks, and the House Intelligence and Financial Services Committees.

Trump's legal team has argued the subpoenas exceed the authority of Congress, but U.S. District Judge Edgardo Ramos found they do, in fact, fall under Congress' authority to conduct investigations to further legislation, Reuters reports. Tim O'Donnell

Norway's foreign ministry confirmed on Saturday that delegates from both Venezuelan President Nicolás Maduro's government and the country's opposition led by Juan Guaidó will meet in Oslo next week to negotiate an end to Venezuela's political crisis.

Both sides met separately with Norwegian mediators last week for preliminary talks. Guaidó has been hesitant about sending representatives to meet with the government, arguing Maduro has used negotiations as nothing more than a stalling tactic in the past. But as the opposition continues to lose momentum, he confirmed he would support the Oslo talks during a rally on Saturday, though he insisted his side would maintain that a transfer of power is necessary. The U.S. State Department shares that sentiment. "As we have stated repeatedly, we believe the only thing to negotiate with Nicolás Maduro is the conditions of his departure," department spokeswoman Morgan Ortagus said.

Maduro has also publicly endorsed the Norway talks, but has shown no indication he would step down.

Norway has a history of successfully mediating foreign internal conflicts, including situations in Colombia, Sri Lanka, and the Philippines. Tim O'Donnell
