In today's newsletter: The Philadelphia Eagles shut out a Kansas City Chiefs three-peat. Experts warn of a "constitutional crisis" as JD Vance questions judicial authority. And a look at why well-made clothing is hard to come by these days.

Here's what to know today.

The Philadelphia Eagles defeated the Kansas City Chiefs to win their second Super Bowl title. The Eagles dominated from the start, dethroning the Chiefs in a rout that delivered the Eagles their second championship in seven seasons.

Sports reporter Rohan Nadkarni recaps the historic night in the NFL:

The Philadelphia Eagles dominated the Kansas City Chiefs to win Super Bowl 59, cruising to a 40-22 victory. The Eagles’ defense completely suffocated the Chiefs’ offense, holding Patrick Mahomes and Co. 275 total yards. Philadelphia also intercepted Mahomes twice, returning one of them for a touchdown in the first half.

The best unit of the game was the Eagles’ defensive line. Kansas City’s offense had no answer for the Eagles’ pass rush. Mahomes was sacked six times, and on both of his interceptions pressure played a factor. With Mahomes not given enough time to throw, the Chiefs were unable to sustain drives, allowing Philly to completely control time of possession.

The big win quiets the noise on some Eagles stars. Quarterback Jalen Hurts has been criticized for his limitation as a passer, but now he has a Super Bowl win over Mahomes on his belt — something only Tom Brady also has. It’s also a big win for head coach Nick Sirianni, who entered this season in the hot seat.

The loss quells some of the “greatest dynasty ever” talk around Kansas City, and is also a pretty significant black mark in Mahomes’s case as the greatest quarterback of all time.

The Chiefs entered the game looking for their third Super Bowl win in a row — something no team had done in NFL history — but instead looked like a far cry from the team that’s flummoxed the league for three of the last four seasons.

'Constitutional crisis': JD Vance and Elon Musk question judges’ authority over Trump

Experts warned that the United States could be headed toward a “constitutional crisis” or a “breakdown of the system” after Vice President JD Vance suggested judges don’t have jurisdiction over President Donald Trump’s “legitimate power.”

"If a judge tried to tell a general how to conduct a military operation, that would be illegal. If a judge tried to command the attorney general in how to use her discretion as a prosecutor, that’s also illegal," Vance wrote on X, adding, "Judges aren’t allowed to control the executive’s legitimate power."

It wasn't clear what judge or court order Vance was referring to or whether he was making a broad statement.

Some of Trump’s executive orders have already been challenged in over two dozen lawsuits, and judges have temporarily halted a number of them. Jamal Greene, a professor at Columbia Law School, pointed out that others in Trump's orbit, including Elon Musk, have floated ignoring court orders. Greene said, "Given the context of which [Vance's post] has happened, it seems to be a winking suggestion that maybe ignoring a court order is on the table."

New series of winter storms to bring more snow and freezing temperatures to northern U.S.

Two more storm systems are expected to hit the northern United States in succession this week, just as a different bout of severe weather across the Northeast begins to slow down. The weekend storm wreaked havoc on roadways and delayed travel in the skies.

The first of the upcoming systems will start from the Plains on Monday, creating snow in the north and heavy rains in the south. The heaviest snow is expected to hit Kansas, with a potential of 2 to 5 inches across the state. On Tuesday, the storm system is predicted to expand east, infiltrating the Appalachian and mid-Atlantic regions. The next storm system will follow soon after on Wednesday, casting another round of widespread rain and snow over the Plains and the Midwest before it moves fully into the Northeast. Here's what else to know.

New clothes feel cheap? They really don't make them like they used to

If it feels difficult to find high-quality clothes these days, you’re not imagining it. Many U.S. clothing companies are cutting corners, opting for lower-quality fabric to keep costs to consumers low while protecting their profit margins. Domestic brands are also struggling to compete in a complex market – American shoppers are flocking to foreign fast-fashion brands like Shein for cheap apparel. Our story examines these challenges, and provides expert advice to frustrated consumers.
