The Constitution assigns Congress the sole authority to declare war, a decision Founding Fathers like George Mason made because they believed the executive branch was not "safely to be trusted with it." Once war has been declared, however, the president is commander in chief, which means he can use weapons — including nuclear warheads — at his discretion.

Members of the Senate Foreign Relations Committee, led by Sen. Bob Corker (R-Tenn.), have noticed that's an awful lot of destruction resting on the decision of a single person, so the committee will hold a hearing Tuesday to reconsider the president's power to launch a nuclear strike. Though the hearing has been cast in more general terms, the immediate impetus appears to be President Trump, who has threatened to "totally destroy" North Korea with "fire and fury" in a preventive strike.

Corker, who has become a vocal Trump critic within the president's party, argues the hearing is "long overdue." But the Trump administration says the current system is working just fine, maintaining that it is necessary for the president to be able to launch a nuclear strike quickly, without the delay of congressional authorization.

A California woman forced to abandon her dog in the Camp Fire came back almost a month later to find he had survived and was waiting for her the whole time.

Andrea Gaylord's two dogs, Madison and Miguel, were left behind when residents of Paradise received an evacuation order since she wasn't able to retrieve them as the fire spread; the K9 Paw Print Rescue group writes that she "hoped and prayed" they would be okay. A volunteer was able to find Miguel, and another left food and water out for Madison, CNN reports.

Gaylord was naturally anxious to return home, and when she was finally allowed to do so this week, she found Madison sitting right there on the property weeks later, even as the home had been completely destroyed, reports USA Today. "Imagine the loyalty of hanging in in the worst of circumstances and being here waiting," Gaylord said. "It was so emotional." Brendan Morrow

Accused Russian spy Maria Butina may be about to plead guilty.

Butina's attorneys on Monday filed a request for her to withdraw her previous plea of not guilty, The Washington Post reports. CNN writes that she looks to have reached a plea deal with the Justice Department, although any further details, including what she would be pleading guilty to, are currently unclear.

Five months ago, Butina was arrested and charged with one count of conspiracy and one of acting as an agent to a foreign government. She has been accused of spending years attempting to influence American policy by forging relationships with prominent conservatives, including with the National Rifle Association, while keeping in contact with Russians, per CNN. Butina's lawyers have argued that she was simply interested in improving Russia's relationship with the United States, The Associated Press reports. Her arrest was not a part of Special Counsel Robert Mueller's investigation into Russian interference in the 2016 election.

However, The New York Times reports that any plea deal would likely require cooperation with ongoing investigations, leaving open the possibility that she could provide them with some key information. Brendan Morrow

Ready to start off your week being utterly repulsed at the sight of a new live-action Sonic the Hedgehog?

Paramount on Monday released the first poster for the upcoming Sonic movie, which will combine live-action and animation à la Who Framed Roger Rabbit?. The look of Sonic is unique to say the least, and downright disturbing to say the most. For whatever reason, the beloved video game character looks strangely human and unexpectedly buff on the poster, less like a cartoon hedgehog and more like a track and field athlete dressing as Sonic for Halloween. Considering he's a hedgehog, he's also a lot furrier than expected, as were a lot of the Pokemon in the recent trailer for the live-action Detective Pikachu movie.

The film's producers insisted in an interview with IGN that Sonic's new look was necessary so that he would fit in with the live-action world. "He's not going to feel like a Pixar character would because I don't think that's the right aesthetic to make it feel like part of our world," producer Tim Miller said. Speaking about Sonic's speed, Miller again stressed the importance of "keeping it grounded and keeping it realistic," because if there's anything that has defined Sonic, a video game franchise about a blue hedgehog that looks very little like a hedgehog and who pursues an evil mustachioed scientist by traveling at lightning speeds, it's grounded realism.

The Sonic the Hedgehog movie, which will feature Ben Schwartz as Sonic and Jim Carrey as Dr. Robotnik, hits theaters in November 2019. Brendan Morrow

Planned Parenthood just won a significant victory as the Supreme Court declined to hear a case from states looking to partially defund the organization.

Louisiana and Kansas had passed laws preventing their citizens from using Medicaid for Planned Parenthood's services that aren't related to abortions, such as ultrasounds, per NPR. Medicaid funding already can't be used for abortions at Planned Parenthood except in cases of rape, incest, or when the life of the mother in danger, per NBC News.

Medicaid patients had filed a lawsuit, and after Louisiana and Kansas suffered defeats in the lower courts, they appealed to the Supreme Court, arguing that the patients could not actually challenge its decisions related to Medicaid funding and that only the federal government could do that, per CBS News. Justices Clarence Thomas, Samuel Alito, and Neil Gorsuch argued in favor of the court taking the case in order to make that determination, NBC News reports.

But the conservative justices came one vote shy of having enough to hear the case. The decision of the lower courts, therefore, stands. Interestingly, Justice Brett Kavanaugh did not join his conservative colleagues in calling for the case to be taken up. CNN reports that he likely would "rather avoid contentious, high-profile disputes for now, at least where possible."

NPR notes that while Medicaid funding can still being used for Planned Parenthood in most states, this decision doesn't mean no states can block the funding — Arkansas, Iowa, Minnesota, Missouri, Nebraska, North Dakota and South Dakota can still do so due to a decision from the Eighth Circuit Court of Appeals.

As President Trump looks for a new chief of staff candidate after being turned down by his top choice, a former officeholder is offering some advice.

Rahm Emanuel, who was chief of staff for former President Barack Obama, wrote in The Atlantic that no matter who Trump picks to replace outgoing Chief of Staff John Kelly, he or she won't be able to function the way a typical chief of staff does as long as Trump continues to "outsource significant authority to Jared Kushner, Ivanka Trump, and other staffers." In fact, Emanuel suggests that whoever is hired "won't really be the chief of staff" because Trump is "unwilling to give anyone the authority needed to perform that job."

And what does Emanuel see as being needed? Well, he notes that Trump appears to be selecting Kelly's successor based on who can help him win re-election in 2020, which Emanuel sees as the wrong move. After all, there will be "other battles to fight" long before then, namely investigations from House Democrats and the impending report from Special Counsel Robert Mueller into Russian interference in the 2016 election. What Trump really needs, Emanuel argues, is a "true wartime consigliere" who can help him manage "what is likely to be an incredibly damaging set of allegations." In other words, he needs a "steady hand." Whoever it is, Emanuel hopes this person will be "unusually good at protecting the rest of us from the president's penchant for self-destruction."

It's unclear who the president might end up selecting, but it doesn't sound like he's going to heed Emanuel's advice — CNN's Kaitlan Collins reports that Trump "wants his next chief of staff to be all politics, politics, politics." Brendan Morrow

Sports Illustrated on Monday announced the Golden State Warriors as its 2018 Sportsperson of the Year — the first team to win the honor since the Boston Red Sox in 2004, and the fourth overall since the magazine introduced the title in 1954.

The Kevin Durant-led Warriors swept LeBron James' Cleveland Cavaliers to win their third championship in four years in June. The victory helped the team beat out actual sportspeople for the Sports Illustrated award, such as the Washington Capitals' Alex Ovechkin, snowboarder Chloe Kim, and resurgent golfer Tiger Woods.

"It was impossible to overlook the influence that the Warriors, as a collective group, have had on their sport and the broader culture over the last half-decade," Chris Stone, SI's editor-in-chief, said in announcing the honor. "They are a generational phenomenon, the likes of which we might not see again for decades, if at all." The Phoenix Suns, currently 4-22, could not be reached for comment about the snub. Jacob Lambert
