Dreaming of a penthouse with incredible views? Well, there’s one for sale atop the world’s skinniest skyscraper that overlooks Central Park in New York City and features five bedrooms, six bathrooms, two terraces, a bar and a screening room. It will, however, set you back a whopping $110 million. Here’s what else you need to know to Get Up to Speed and On with Your Day. “I think it’s going very well,” President Donald Trump told reporters on Thursday in the wake of his decision to enact 10% tariffs on imports from any country into the US and even higher tariffs for 60 other trading partners this week. The tariffs have already earned the ire of world leaders as well as vows of retaliation, rattled global markets and prompted at least five US auto plants to lay off hundreds of workers. The administration’s attempt to spin the escalating trade war it started didn’t help. While Trump said the tariffs “give us great power to negotiate,” his top trade adviser, Peter Navarro, told Fox News: “This is not a negotiation.” And Vice President JD Vance said he thought “it could be worse in the markets because this is a big transition.” But that comment fell flat in the face of the worst day on Wall Street in five years and the disappearance of $2.5 trillion from the S&P 500 index. The Dow fell 1,679 points, or about 4%, and the Nasdaq plunged nearly 6%. South Korea’s highest court officially removed President Yoon Suk Yeol from office today. The ruling ended four months of political turmoil and legal wrangling that Yoon created when he declared martial law in December and sent soldiers into parliament to “drag out” lawmakers. He claimed his actions were justified by political deadlock and threats from “anti-state forces.” The lawmakers responded by pushing past the troops and gates, voting to overturn Yoon’s decree and later, impeaching him. Moon Hyung-bae, the Constitutional Court’s head judge, said the martial law decree was unconstitutional because there was no grave national crisis at the time and thus could not be justified. Yoon still faces criminal charges that could land him in prison for life. A general election to choose a new president must be held within the next 60 days. In a major shakeup of the US intelligence community, the Trump administration has fired the director and the deputy director of the National Security Agency. It’s not yet known why Gen. Timothy Haugh, who also leads US Cyber Command, and Wendy Noble, Haugh’s deputy at NSA, were terminated. “NSA mission is vast and extremely complicated,” Renée Burton, a cybersecurity expert who spent more than two decades at the NSA, told CNN. “General Haugh and Ms. Noble have built the expertise and credibility it takes to oversee such a vital part of our national security. Replacing them will not be easy and the disruption will expose the country to new risk.” Lt. Gen. William Hartman, the current Cyber Command deputy director, is expected to serve as acting head of the command and NSA, two former officials said. A Pentagon watchdog has announced plans to launch an investigation of Secretary of Defense Pete Hegseth for discussing a US military attack on Houthis in Yemen with other national security officials in a group chat on Signal — a conversation that inadvertently included a journalist. In a letter to Hegseth, Acting Inspector General Steven Stebbins said that the “evaluation” will seek to determine if the secretary and other Pentagon personnel “complied with DoD policies and procedures for the use of a commercial messaging application for official business.” The probe will also examine if Hegseth followed classification and records retention requirements. Earlier this week, the White House closed its investigation into the security breach and declined to elaborate on what, if any, steps had been taken.
