Donald Trump got word from his security detail in Cedar Rapids on Monday that there could be someone in the audience with tomatoes — so Trump reportedly decided to go ahead and take precautions.

"If you see somebody getting ready to throw a tomato, knock the crap out of them," Trump urged his supporters. Were anyone to feel concern about being prosecuted for assault in such a scenario, Trump reassured that, "I promise you, I will pay for the legal fees."

The European Union is preparing to apply 25 percent tariffs on $3.5 billion worth of American goods in retaliation for President Trump's proposed steel and aluminum tariffs, Bloomberg Politics reports. A number of products targeted on the EU's list seem especially chosen to put maximum pressure on lawmakers including bourbon whiskey, which comes from Senate Majority Leader Mitch McConnell's (R-Ky.) state, and jeans, with Levi Strauss' headquarters located in House Minority Leader Nancy Pelosi's (D-Calif.) congressional district.

The EU tariffs would also target motorcycles, cosmetics, ladders, and T-shirts, as well as agricultural products and steel products. Even before the report about the EU tariffs, The New York Times estimated that more than 170,000 Americans could lose their jobs under Trump's tariff plan due to the higher cost of doing business.

Despite pressure from within his own party, Trump has publicly refused to compromise. "We're not backing down," he promised Monday. On Sunday, British Prime Minister Theresa May called to express her concerns about the U.S. sparking a trade war with the EU, and Trump privately said he had not reached a final decision yet, The New York Times reports.

The 2018 midterm elections are off to the races, with the first primaries of the year being held Tuesday in Texas. All eyes are on the Democrats, who are hoping to turn the state purple as part of their nationwide effort to flip the House. The party is running candidates in all of the state's 36 congressional districts for the first time in 25 years, Politico reports.

While the polls officially open at 7 a.m. CST, early voting numbers already indicate an energized Democratic Party, The Texas Tribune writes: "Overall, 370,219 Democrats voted early in [the 10 counties with the highest number of registered voters] compared to 282,928 Republicans … That means Democratic turnout more than doubled from four years ago, while Republican turnout rose less than 15 percent."

The deputy director of Texas Democrats, Manny Garcia, expressed his excitement to The Washington Post: "If Texas votes like it looks, then Democrats win," he said.

One of the most significant races will be in the 7th District, in the Houston suburbs. Democrats in Washington are opposing progressive activist Laura Moser, who they view as a weaker candidate against Rep. John Abney Culberson (R). Because Texas primary candidates need more than 50 percent of the vote to avoid a runoff, Moser is aiming to make it to the top two in a race that has six candidates on the Democratic side.

There is also a Bush in the race: Incumbent Land Commissioner George P. Bush, the son of Jeb Bush, is being threatened by Jerry Patterson over — what else? — his stewardship of the Alamo.

A 10-member delegation from South Korea returned from a short trip to Pyongyang on Tuesday with an agreement for North Korean leader Kim Jong Un and South Korean President Moon Jae-in to meet in April, set up a telephone hotline between the two leaders, and put North Korean denuclearization on the table for discussion, South Korean national security director Chung Eui-yong announced in Seoul. Chung led the delegation, the first South Korean officials to meet Kim. Chung led the delegation, the first South Korean officials to meet Kim. Kim hosted the group for dinner Monday night along with his sister, Kim Yo Jong, and in a rare appearance, his wife, Ri Sol Ju.

Chung said North Korea had indicated it is ready for a "heart-to-heart" with Washington on everything from normalizing relationships and denuclearization, The Associated Press reports. He added that Pyongyang said it did not need nuclear weapons if the U.S. withdrew all military threats and would not attack South Korea with nukes or conventional weapons. North Korea has promised to freeze its nuclear program before and reneged, BBC News notes. The U.S. said it is "cautiously optimistic" about the North-South thaw. South Korean officials will head to Washington next to brief U.S. lawmakers on the rare meeting with North Korean leaders. Peter Weber

Chelsea Clinton was on Monday's Late Show to talk about her new children's book, She Persisted Around the World, but of course that's not where Stephen Colbert began the conversation. "Now, your family has a particularly unique relationship emotionally to the fact that Donald Trump is president of the United States," he said. "Stephen, I think that a lot of us have pretty unique emotional relationships to the fact that Donald Trump is president," Clinton genially fired back.

Colbert asked what the Clinton family does to cope with Trump, what kind of conversations they have, and Clinton talked about policy and candidates. "Unfortunately, this administration is kind of the collision of cruelty and incompetence," she said at the end of a lengthy answer. "Does your entire family speak in paragraphs?" Colbert asked, practically begging her to show some anger. She declined.

"There has been some criticism of Ivanka Trump recently, of her role in the White House, or whether she should have a role in the White House," Colbert said. "You were 20 when your father left office, but certainly you understand what it's like to be the child of the president. Were you asked to fix Middle East peace at any point?" Clinton said she was mostly asked about her homework, and when Colbert pressed, she said she thinks Ivanka Trump is fair game for criticism regarding her decisions or President Trump's policies, as with his other employees. Colbert asked if Clinton and Ivanka are still friends. They were friends, she said, but "I haven't spoken to her in a long time," and policy has definitely clouded their friendship. Watch below.

For some reason, Sam Nunberg, a former adviser to President Trump's campaign, decided to immolate on cable news Monday afternoon, appearing multiple times on MSNBC, CNN, and NY1, and conducting phone interviews with news organizations. Among other jaw-dropping statements, Nunberg said Trump knew about a meeting with Kremlin-linked lawyers, lobbed personal attacks at White House Press Secretary Sarah Huckabee Sanders, and taunted Special Counsel Robert Mueller, who has subpoenaed his correspondence with several people in Trump' s inner circle. He certainly got everyone's attention.

By Monday night, Nunberg was telling The Associated Press he is probably "going to end up cooperating with" Mueller's investigators after all, but after his "wild, unscripted, and unrestrained antics," ABC News' Kendis Gibson said Tuesday morning, "Nunberg's mental stability is being called into question, and some are saying that he was actually just drunk last night."

Among those suggesting that Nunberg was impaired was a "Trump ally" who told CNN's Erin Burnett that Nunberg was "drunk or off his meds," in her paraphrasing.

Burnett brought it up again. "Talking to you, I have smelled alcohol on your breath," she told Nunberg. "Well, I've not had a drink," he replied. "You haven't had a drink? Because it is the talk out there," she pressed. "My answer is no, I have not," Nunberg said. "No. Besides my meds. Anti-depressants. Is that okay?"

The meds are okay, but as Nunberg suggested, he may need to find a new lawyer. Peter Weber

On Monday night, a very tired Jimmy Kimmel pulled back the curtain a bit on Sunday night's Academy Awards, which he hosted, explaining that his crew built the hot-dog cannon especially for the Oscars, good-naturedly griping about his mother embarrassing him by passing out Oscar-shaped cookies to A-listers during the award ceremony, and detailing the lengths his legal team went to in order to ensure they gave a jet ski to the award recipient with the shortest speech. There was some real drama at the after-party, too, he explained.

Best actress winner "Frances McDormand was robbed last night, but not in the usual way people are robbed at the Oscars," Kimmel said. After she won, "she gave an incredible speech, and then at the after-party, she put her Oscar down on the table and someone snatched it. And after the guy snatched it, he did the smart thing: He immediately made a video of himself and posted it on Facebook. ... So then he was arrested for grand theft, which is a felony. And not only is that dumb, it's dangerous. I would rather steal from Mike Tyson than Frances McDormand — she'll beat your ass! And what's the long-term plan when you steal an Oscar? Hope your friends didn't notice you didn't win Best Actress in 2018?" Watch below. Peter Weber

Last week, Stephen Colbert flew down to Washington with his own "memo" on House Intelligence Committee Chairman Devin Nunes (R-Calif.), and he had some fun at Nunes' expense with the committee's top Democrat, Rep. Adam Schiff, and even Sen. Jeff Flake (R-Ariz.). "As much fun as we had down there, ultimately what we wanted was for Devin Nunes to respond to us, a comedy show," Colbert said on Monday's Late Show. "But say what you want about the guy, he's not that dumb — is what I thought." He played a clip of Nunes complaining about Colbert on Fox News. "He took the bait!" Colbert said.

Nunes told Fox News that Colbert is part of the "danger" the left poses to America, and when asked if Colbert even tried to contact him for the show, he replied, "Not that I know of." Colbert had the footage. "Either your staff didn't tell you that I charged into your office, or you're not telling the truth," he said. "So is Devin Nunes a liar? Not that I know of." Colbert played some outtakes from his interview with Schiff, then summarized Nunes' view of the situation: President Trump, who openly asked Russia to hack Hillary Clinton's emails, is good for America; Stephen Colbert, a comedian, is "a danger."

In the full video from Friday, Colbert failed to get much information about the Russia investigation from Schiff or the top Democrat on the Senate Intelligence Committee, Sen. Mark Warner (Va.), but he at least made Schiff laugh. Warner? "I mean this as a compliment — you look dead inside," Colbert told the senator. "I appreciate that," Warner said. Watch below. Peter Weber
