A lot has changed since 2012 — four years after he ran against President Obama, Mitt Romney received cheers at the Democratic National Convention.

Romney appeared in a video that featured prominent Republicans and conservatives commenting on their opposition to Trump. He wasn't the only one to get applause — Sen. Lindsey Graham (R-S.C.) and former New York Gov. George Pataki were also well-received. After the video played, John Hutson, a retired rear admiral and former judge advocate general, came onstage, and announced, "Unlike Donald Trump, there are two things that I know an awful lot about: Law and order." He called Trump out for "endorsing torture at a minimum" and inviting Russia to hack a U.S. entity. "It's embarrassing enough that he's the face of one of our political parties," Hutson said. "The real disaster would be if we let Donald Trump become the face of the country we love."

Hutson urged people to listen to the more than 120 Republican national security leaders who have warned that Trump would "make America less safe," and brought up Trump's comments on Sen. John McCain (R-Ariz.). "I served in the same Navy as John McCain," he said. "I used to vote in the same party as John McCain. Donald, you're not fit to polish John McCain's boots." The room erupted in more unlikely cheers, this time not for McCain the Republican, but McCain the war hero. Catherine Garcia

On Thursday, President Trump announced that he was pulling out of a scheduled summit with North Korean leader Kim Jong Un by … writing a civil, calm, professionally regretful letter? Still, despite the generally cordial tone, this is distinctly a work from the Trump canon.

The first clue comes in the second sentence: "We were informed that the meeting was requested by North Korea, but that to us is totally irrelevant." Then why bring it up? While the next sentence, "I was very much looking forward to being there with you," might be translated as "I really want the Nobel Prize," the subsequent sentence uses Trump's favorite word ("sad!") and displays his usual love of hyperbolic adjectives: "Sadly, based on the tremendous anger and open hostility displayed in your most recent statement, I feel it is inappropriate, at this time, to have this long-planned meeting."

The letter even sneaks in a Trumpian boast at the bottom of the first paragraph: "You talk about your nuclear capabilities, but ours are so massive and powerful that I pray to God they will never have to be used."

While admittedly the letter isn't littered with ellipsis, threats, typos, oddly Capitalized letters, or addressed to Mr. Rocket Man, Trump's own staff have reportedly learned to mimic his rambling, colorful messages in order to ghostwrite them more effectively. Apparently that goes to open letters to foreign heads of state, too. Jeva Lange

The summit between President Trump and North Korean leader Kim Jong Un may be canceled, but the commemorative coins will live on forever.

Trump on Thursday pulled out of the summit that was scheduled for June 12 in Singapore, writing to Kim that "it is inappropriate, at this time, to have this long-planned meeting" due to increasing tensions. But the souvenir coins that the White House Communications Agency minted earlier this week are still for sale through the White House gift shop.

(The White House Gift Shop)

The coin celebrated the "PEACE TALKS" of 2018, depicting Trump and Kim facing off with both national flags. Patriotic collectors can still visit the White House gift shop online and pre-order a coin for just $24.95, though it's a different version that includes South Korean President Moon Jae-In. It even comes in a black velvet coin case!

If coins aren't your thing but you still want to remember the almost-talks, don't worry — The White House is still taking orders for the official Nuclear Deproliferation Summit Ornament. The shop says its the most sophisticated ornament design yet, made to complement the summit coin.

So buy your souvenirs now: If not to commemorate a successful summit, then to wistfully sigh and remember what could have been. Summer Meza

President Trump and his allies have been attacking former Director of National Intelligence James Clapper over the past few days, part of his attempt to make "Spygate" happen. Clapper is on a media tour to promote his new book, Facts and Fears, and along with explaining how Trump is distorting his words and the FBI's attempt to investigate Russia, Clapper has been explaining his contention in the book that the Russians, to their surprise, "swung the election to a Trump win."

"Since I left the government," Clapper told PBS NewsHour on Wednesday, "it's what I call my informed opinion that given the massive effort the Russians made, the number of citizens that they touched, and the variety and the multidimensional aspects of what they did to influence opinion and affect the election, and given the fact that it turned on less than 80,000 votes in three states, to me it just exceeds logic and credulity that they didn't affect the election, and it's my belief they actually turned it."

On CNN Thursday night, Clapper swatted down more Trump team attacks and reiterated his "informed opinion" about Russia handing the election to Trump, though, he told Jake Tapper, "I don't have the empirical evidence to go with it."

But there is some empirical evidence, if not conclusive, in a new working paper at the National Bureau of Economic Research. Automated Twitter bots — a key tool that Russians used in the election — may have added 3.23 percentage points to Trump's vote in 2016, as well as 1.76 percentage points to the "leave" vote in Britain's Brexit campaign, the researchers found. "Our results suggest that, given narrow margins of victories in each vote, bots' effect was likely marginal but possibly large enough to affect the outcomes," write authors Yuriy Gorodnichenko from U.C. Berkeley and Tho Pham and Oleksandr Talavera from Britain's Swansea University. You can read more about the study at Bloomberg News. Peter Weber

President Trump has pulled out of a historic summit in Singapore with North Korean Leader Kim Jong Un, which had been scheduled for June 12, calling it "a truly sad moment in history."

In an open letter, Trump told Kim "we greatly appreciate your time, patience, and effort with respect to our recent negotiations" and that "I was very much looking forward to being there with you," but that "it is inappropriate, at this time, to have this long-planned meeting" due to increasing tensions between the parties. A North Korean vice minister of foreign affairs called Vice President Mike Pence "ignorant" and "stupid" on Thursday for comparing North Korea to Libya, and warned Kim would cancel the summit if the U.S. didn't stop its threats.

Tensions between two of the Trump administration's economic advisers has surpassed the usual co-worker drama.

Treasury Secretary Steven Mnuchin and top trade adviser Peter Navarro have not resolved their differences when it comes to economic policy opinions, The Daily Beast reported Thursday, and sources say Navarro has taken to calling Mnuchin "Neville Chamberlain."

That former U.K. prime minister famously capitulated to Nazi Germany and fascist dictator Adolf Hitler during the late 1930s. Navarro reportedly sees China as such a serious economic threat that he thinks Mnuchin's international policy principles make him just as bad as a Nazi appeaser.

Navarro takes an "America First" stance when it comes to trade policies, The Daily Beast reports, and is very frustrated that other advisers like Mnuchin don't want to be as tough on China as he'd like. One official said that the battle between the two advisers is like a "cold war that became hot," also referring to a shouting match between Mnuchin and Navarro while in China earlier this month.

The U.K. is blaming Russia for a prank phone call to Foreign Secretary Boris Johnson, with Johnson's deputy, Alan Duncan, telling Bloomberg News: "If this was an attempt to ridicule us, it has totally backfired." Russian pranksters have previously placed hoax calls to U.S. politicians by posing as world leaders; earlier this year, radio comedians "Vovan" and "Lexus" pretended to be the speaker of the Ukrainian Parliament in order to offer Rep. Adam Schiff (D-Calif.) nude photos of President Trump, and U.N. Ambassador Nikki Haley was tricked into telling the pranksters she was "closely watching" Russia's interference in the elections of Binomo, a made-up country.

Johnson apparently realized the call was a hoax and ended the conversation, earning the respect of prankster Alexei Stolyarov who claimed it was "probably the first time the person we talked to ... was not a fool."

The U.K. was not amused, suggesting that the Kremlin supported the call in an attempt to discredit reports that Russia poisoned former spy Sergei Skripal and his daughter in England. "These childish actions show the lack of seriousness of the caller and those behind him," said the Foreign Office. Jeva Lange

President Trump and his allies have spent the past week stoking unfounded fears that the Deep State planted a spy in his 2016 presidential campaign, and Trump didn't let up on Thursday, tweeting:

Trump was immediately called out on his lies. Former Director of National Intelligence James Clapper actually said the opposite of what Trump claims, Politifact reports: Clapper's exact quote when asked "was the FBI spying on Trump's campaign" was, "No, they were not. They were spying on — a term I don't particularly like — but on what the Russians were doing."

There is no publicly available evidence that there was any politically motivated spying on Trump's campaign. Rather, an FBI informant spoke with two Trump campaign advisers in 2016 after being alerted to suspicious contacts with Russia. "Accusations that the FBI was 'spying' on the Trump campaign — rather than spying on foreign spies, which is its job — erase the important distinctions between counterintelligence and criminal investigations," argued Asha Rangappa at The Washington Post.

Many critics believe Trump is intentionally branding the intelligence community as partisan as a means of discrediting Special Counsel Robert Mueller's investigation. Read how Trump's strategy might just be crazy enough to work here at The Week. Jeva Lange
