It apparently took a private plane ride to convince Sen. Bernie Sanders (I-Vt.) to campaign for Hillary Clinton.

After begrudgingly withdrawing from the presidential race in 2016, Sanders started stumping for his former rival across the country. But before he agreed to do so, Sanders demanded private flights from venue to venue, costing the Clinton campaign $100,000 in all, six Clinton campaign staffers tell Politico

Ex-Clinton staffers have been eager to call out what they see as Sanders' lackluster efforts to defeat President Trump, citing his earlier criticism of Clinton and how long he waited before dropping out of the primary. When Sanders finally did withdraw, those Clinton staffers say they expected him to fly commercial "90 percent of the time." That didn't happen, as the Clinton campaign's director of rapid response Zac Petkanas snidely describes:

“I'm not shocked that while thousands of volunteers braved the heat and cold to knock on doors until their fingers bled in a desperate effort to stop Donald Trump, his Royal Majesty King Bernie Sanders would only deign to leave his plush D.C. office or his brand new second home on the lake if he was flown around on a cushy private jet like a billionaire master of the universe."

Sanders spokesperson Arianna Jones said the private planes were used to ensure the senator "could get to as many locations as quickly as possible" and defended his "grueling" tour in support of Clinton. Sanders has also racked up another $324,000 in private jet flights in the two years since the presidential election, paid for by his Senate campaign committee, Politico also notes.

President Trump responded early Monday morning to a tweet made by foreign policy expert and NYU political science professor Ian Bremmer.

Bremmer on Sunday tweeted a fake quote attributed to the president, which he later deleted after backlash from journalists, political analysts, and Twitter users everywhere. Bremmer attempted to justify his fake tweet before deleting it, saying that the quote was "kinda plausible" and that that was "the point."

Trump fired back early Monday morning, panning the "age of Fake News" and the news media. "People think they can say anything and get away with it," Trump tweeted.

Trump, who has 233 statements rated as false on PolitiFact, called for libel laws to be modified to hold journalists accountable. But it's unclear whether he has the power to do so, Fox News reported. In response to Trump's earlier calls to change libel laws, Brian Hauss, a staff attorney with the American Civil Liberties Union, said that "the president does not have the authority" to change libel laws, since they fall under state, rather than federal, jurisdiction.

Preliminary results of the European Union parliamentary elections show that nationalist parties gained significant ground in the U.K., France, Italy, and Poland. Parties like Britain's Brexit party, led by Nigel Farage, and France's National Rally party, led by far-right figurehead Marine Le Pen, took the most votes in their home countries.

However, Reuters reported, these victories in individual countries still didn't "dramatically alter the balance of pro-European power in EU assembly." Pro-Europe groups, including the Progressive Alliance of Socialists and Democrats and the Greens/European Free Alliance party, held strong with 504 out of the 751 available seats in Parliament. The EU's new priority will be "the search for a majority," as no single party took enough seats to hold a simple majority.

Europeans managed to sharply buck the norm of low voter turnout at EU Parliament elections. This time, 51 percent of eligible voters cast their vote, the highest turnout in 20 years. Back in 2014, that figure was only 43 percent. But renewed nationalist sentiment, along with its opposition, seems to have invigorated European voters enough to reverse the trend of "falling participation since the first direct EU vote in 1979."

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
