President Trump says that if negotiations with Democrats don't work out, he may opt to build his border wall without Congress' approval.

Trump in a press conference Friday was asked if he has considered declaring a national emergency to get the wall built, and he confirmed that he has. "And I can do it if I want," Trump added. "Absolutely we can call a national emergency because of the security of our country. Absolutely."

Trump went further to say that he "may" do this, although he'd apparently prefer to get the wall funded by negotiating with Congress. "We're giving that a shot," Trump said.

This question came just after ABC News published a report that Trump is "seriously considering" this option. Democrats have repeatedly refused to provide Trump with the $5 billion in border wall funding he has requested, while Trump threatens to leave the government shut down for "years" if they don't cave. He has previously referenced the state of border security as a "national emergency." Brendan Morrow

Tesla CEO Elon Musk poked fun at himself during his Saturday Night Live monologue, joking about his lack of "intonational variation," his marijuana-themed appearance on Joe Rogan's podcast, the spelling of his son's name, and some of his odder tweets.

"Look, I know I sometimes say or post strange things," Musk said, seemingly addressing the controversy surrounding the show's choice to have him host. "But that's just how my brain works. To anyone I've offended, I just want to say: I re-invented electric cars and I'm sending people to Mars in a rocket ship. Did you also think I was gonna be a chill, normal dude?"

Musk also revealed he has Asperger's syndrome, reportedly marking the first time he has spoken publicly about the diagnosis. Watch the full monologue below. Tim O'Donnell

China's Long March 5B rocket crashed back to Earth on Sunday morning, landing in the Indian Ocean just west of the Maldives, the China Manned Space Agency announced. Most of the debris from the rocket, which was launched in April, reportedly burned up when it re-entered the Earth's atmosphere.

The risk of the rocket causing significant damage was considered low, but experts were concerned because the 40,000-pound Long March was out of control and traveling at a high speed, making it very difficult to predict where it would land.

While it appears the worst was avoided (it's unclear if any debris landed on the Maldives, CNN notes), NASA Administrator Bill Nelson still expressed displeasure with Beijing. "Spacefaring nations must minimize the risks to people and property on Earth of re-entries of space objects and maximize transparency regarding those operations," he said. "China is failing to meet responsible standards regarding their space debris."

Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics who tracked the rocket, tweeted that regardless of the outcome, China was still "reckless." Read more at CNN and NBC News. Tim O'Donnell

"There is simply no democratic justification whatsoever for [U.K. Prime Minister] Boris Johnson or anyone else seeking to block the right of the people of Scotland to choose our future," Scottish National Party leader and Scotland's First Minister Nicola Sturgeon said Saturday in a victory speech after the SNP won its fourth straight election, while the pro-independence Greens also had a strong showing, meaning a majority of Scottish parliament would back a referendum.

If a vote is blocked Sturgeon added, it "will demonstrate conclusively that the U.K. is not a partnership of equals and astonishingly that Westminster no longer sees it as a voluntary union of nations."

While Sturgeon is expected to pressure Johnson to allow another referendum, the prime minister has said he won't, calling it "irresponsible and reckless."

As for what's happening on the ground with Scottish voters, Prof. John Curtice, whom Bloomberg notes is the U.K.'s "most prominent electoral analyst," said the country is "divided straight down the middle on the constitutional question," which was the driving force behind the highest turnout since 1999. There's no telling which way a vote would go at the moment, so a referendum would be an "enormous political gamble" for both Johnson and Sturgeon, Curtice writes. Read more at BBC and Bloomberg.

Annie Pforzheimer, a longtime diplomat who has extensive experience working in Afghanistan, is concerned about President Biden's plan to withdraw U.S. troops from the country without any conditions from the Taliban by or before Sept. 11, 2021. In a piece for Politico published Saturday, she shares her not uncommon view that the U.S. exit will allow the Taliban an opportunity to "increase their territorial control and dictatorial rule," depriving Afghanistan of much hope for a "normal future." But, at this point, she acknowledges Biden's mind won't change, so she turned her attention to ways the U.S. can employ leverage without forces on the ground.

Pforzheimer's ideas include remaining publicly committed to Afghan security forces, retaining old and imposing new sanctions on the Taliban until they're no longer a threat to Afghanistan's stability, and refusing to recognize a Taliban government if it "denies basic human rights to its citizens." She also argues the U.S. should make sure that "Afghanistan's neighbors, particularly Pakistan and Central Asia ... prioritize their existing trade and energy linkages and press for a peace process that will contribute to regional prosperity." Additionally, she writes, "the Gulf States and other former and current Taliban patrons should understand that a peaceful outcome is a top U.S. government goal."

The Colonial Pipeline, the principal transporter of gasoline and diesel fuel up and down the East Coast of the United States, was temporarily shut down on Friday after its operator, Colonial Pipeline Co., learned it was the victim of a cyberattack.

The attack reportedly involved ransomware and appeared to be limited to information systems, as opposed to operational control systems, but the investigation is still in the early stages. Subsequently, there's no clear sense of who the perpetrator was.

Analysts don't expect the stoppage to negatively affect fuel markets or cause any shortages, so long as it only lasts for a day or two, The Wall Street Journal reports. Still, Tom Kloza, the global head of energy analysis for Oil Price Information Services, told the Journal that targeting the pipeline, which carries roughly 45 percent of the fuel consumed in the United States, is a "big deal" and "could really wreak havoc."

Mike Chapple, a cybersecurity expert at the University of Notre Dame and a former National Security Agency official, added that the pipeline shutdown "sends the message that core elements of our infrastructure continue to be vulnerable to cyberattack," a threat Homeland Security Secretary Alejandro Mayorakas acknowledged as recently as Wednesday, the Journal notes.

The National Republican Congressional Committee did not share internal polling data that showed former President Donald Trump has weak numbers in key battleground districts at a retreat for House Republicans in April, two people familiar with the presentation told The Washington Post. The NRCC staffers reportedly held back the information even when a member of Congress asked them directly about Trump's support.

The Post later obtained the full polling results, reporting that Trump's unfavorable ratings were 15 points higher than his favorable ones, and nearly twice as many voters had a strongly unfavorable view of him than those who had a strongly favorable one. In those same districts, President Biden and Vice President Kamala Harris were both more popular than Trump, the Post notes.

It reportedly wasn't the first time this has happened — Rep. Liz Cheney (R-Wyo.) told colleagues that Republican campaign officials had also glossed over poor Trump polling during a retreat for ranking committee chairs in March, per the Post.

Cheney, you may have heard in recent weeks, is determined to move the GOP away from Trump and she'd likely point to the polling as a reason why, but she's faced a lot of criticism from her colleagues, including House Minority Leader Kevin McCarthy (R-Calif.), who think the party's short-term electoral chances are doomed without the former president leading the charge, and there's no indication their minds will change anytime soon.
