President Trump's button-measuring contest with North Korean leader Kim Jong Un on Tuesday night sparked dark jokes and genuine concern about the possibility of nuclear war. But are articles about the "nuclear war tweet heard 'round the world" exaggerating? CNN's Jake Tapper didn't seem to think so when he appeared on The Lead on Tuesday night, calling Trump's response to Kim's threats something "the world has frankly never before heard from an American president."

Tapper then ominously quoted former President John F. Kennedy: "Every man, woman, and child lives under a nuclear sword of Damocles, hanging by the slenderest of threads, capable of being cut at any moment by accident or miscalculation or by madness." Tapper didn't dance around his concerns, though, adding that "it may be difficult for those of you at home to wrap your minds around a U.S. president who makes statements like this about the use of nuclear weapons, which would of course murder millions of people."

Other anchors and analysts also reacted to Trump's tweet with shock. On Today, NBC national security analyst Jeremy Bash said "this is a tweet that could lead to confrontation and maybe even war." On MSNBC, Lawrence O'Donnell called the tweet proof that the president is "unfit to serve." Speaking to CNN's Anderson Cooper, Rep. Jim Himes (D-Conn.) offered a different perspective: "We've gotten to a weird place where it really doesn't matter what the president of the United States says anymore, because it's so bizarre, strange, not true."

But it was Tapper who summed up Trump's tweet with a grim reminder: "None of this [is] normal, none of this [is] acceptable, none of this [is] — frankly — stable behavior," he said. Jeva Lange

CNN's Jake Tapper made a valiant effort to extract clarity from President Trump's personal attorney, Rudy Giuliani, in an interview on State of the Union Sunday.

Trump "did not have discussions with" his former personal attorney, Michael Cohen, before Cohen gave false congressional testimony, Giuliani said, adding, "certainly [Trump] had no discussions with [Cohen] in which he told him or counseled him to lie."

But with his next breath, Giuliani allowed that some discussions may have happened after all. "If [Trump] had any discussions with [Cohen], they'd be about the version of the events that Michael Cohen gave them, which they all believed was true," he said.

Tapper pressed Giuliani to recognize he'd "just acknowledged that it's possible that President Trump talked to Michael Cohen about his testimony" after denying exactly that, and Giuliani responded with a wealth of answers.

Such a conversation "would be perfectly normal," Giuliani said, before emphasizing that he personally does not know whether it occurred and noting that even if he did know, he might not be able to talk about it because of attorney-client privilege.

All that said, Giuliani concluded, it's "not significant" whether such a conversation happened — which it didn't. Unless it did. Rudy Giuliani doesn't know, and if he did, it's possible he couldn't tell you. Bonnie Kristian

Vice President Mike Pence on Fox News Sunday slammed congressional Democrats' rejection of the immigration policy package President Trump proposed Saturday as a deal to re-open the federal government from its partial shutdown.

"Well, there's a legislative process that is going to begin on Tuesday in the United States Senate" based on Trump's pitch, Pence said, "and it was disappointing to see [House Speaker Nancy Pelosi (D-Calif.)] reject the offer before the president gave his speech. I mean, look, the president is offering a solution, and what we have from Democrat [sic] leadership so far is just soundbites."

There were multiple points of overlap between Trump's plan and the statement Pelosi released shortly before Trump's Saturday remarks, though Pelosi panned Trump's deal as "a compilation of several previously rejected initiatives, each of which is unacceptable and in total, do not represent a good faith effort to restore certainty to people's lives."

Pence also pushed back on claims from immigration hardliners that Trump's offer of "three years of legislative relief" for Deferred Action for Childhood Arrivals (DACA) and temporary protected status (TPS) recipients amounts to amnesty. "This is not amnesty," he said. "There's no pathway to citizenship there's no permanent status here at all, which is what amnesty contemplates."

In a Sunday morning tweet, Trump also said the three-year extension is not amnesty, but he suggested he could accept amnesty in a future immigration deal.

President Trump's former personal attorney Michael Cohen pursued the possibility of a Trump Tower project in Moscow as late as October or November of 2016, Trump's current personal attorney, Rudy Giuliani, said on NBC's Meet the Press Sunday.

Cohen initially told Congress he abandoned the project in January of 2016, as the Republican primary elections began. He later admitted this was a lie and said talks related to the project continued through June of 2016, around the time Trump clinched the GOP nomination.

"Well, it's our understanding [conversations about the project] went on throughout 2016. Weren't a lot of them, but there were conversations," Giuliani told host Chuck Todd. "Can't be sure of the exact date. But the president can remember having conversations with [Cohen] about it ... as far as October, November. Our answers cover until the election."

Trump has repeatedly claimed the Moscow deal ended before his presidential campaign began. "I mean, I have nothing to do with Russia. I don't have any jobs in Russia. I'm all over the world but we're not involved in Russia," he said in July of 2016 — per Giuliani's present account, four to five months before these conversations about the Moscow project ended.

About 170 migrants are missing and feared dead after two shipwrecks in the Mediterranean this week.

Three survivors of one wreck rescued by an Italian naval helicopter on Friday said they'd been on a ship with about 120 people which began sinking after leaving Libya Thursday. A 2-month-old baby was among the passengers. Another 53 people who sailed from Morocco are also missing, though at least one person from that boat was rescued.

"We cannot turn a blind eye to the high numbers of people dying on Europe's doorstep," said a statement from the United Nations' refugee agency. "No effort should be spared, or prevented, from saving lives in distress at sea." Bonnie Kristian

Local authorities by Saturday evening had revised their estimate of deaths in a Friday explosion at a Mexican fuel pipeline to 73, with another 74 people injured in the blast and more still missing.

The death toll was initially put at 21 but quickly rose. Casualties are high because a crowd of hundreds of villagers had gathered in hopes of collecting free gasoline after the pipeline was punctured by fuel thieves. Gas stations in the area have been rationing gasoline because of fuel shortages, and word of the spill from the pipeline spread quickly.

"I trust in the people, and I know that with these painful, regrettable lessons, the people will also distance themselves from these practices" of fuel theft, said Mexican President Andres Manuel Lopez Obrador, who visited the site of the tragedy Saturday. Bonnie Kristian

A dangerous winter storm that brought extreme cold and heavy snow to much of the Midwest on Friday and Saturday moved east to New England Sunday. States of emergency have been declared in New Jersey and Pennsylvania, and widespread travel delays are anticipated.

"Feet of snow, blizzard conditions, a significant build-up of ice, tree-breaking winds, and plunging temperatures will close roads, cause flight cancellations, and disrupt daily activities over a large part of the northeastern United States this weekend," said AccuWeather Senior Meteorologist Alex Sosnowski.

"Be careful and try staying in your house," President Trump tweeted Sunday morning. "Large parts of the Country are suffering from tremendous amounts of snow and near record setting cold. Amazing how big this system is." Bonnie Kristian
