Trump officials tell Congress Iran will be hit with 'overwhelming' firepower in the coming days

Top administration officials told lawmakers in classified briefings yesterday to expect a huge wave of military strikes on Iran in the coming days.

"The amount of firepower coming in the next day or two from us is going to be overwhelming," said GOP Sen. Lindsey Graham, a defense hawk who has long-supported military strikes against Iran.

Briefers for the administration, including Secretary of State Marco Rubio, told members to expect "a very long operation," said Sen. Andy Kim, D-N.J., a former State Department official.

GOP lawmakers said they didn't get the impression that the administration was preparing to put American boots on the ground — but reiterated that President Donald Trump is ruling nothing out.

Meanwhile, Vice President JD Vance's role in selling a war in Iran is clashing with both his experience as an Iraq War veteran and anti-interventionist views.

He has consistently held a more hawkish position on Iran — particularly wanting to curb the country's nuclear capabilities — but made his reservations about combat action in Iran known before last week's military strikes.

The heated Senate Republican primary in Texas will continue for several more weeks, with NBC News projecting that Sen. John Cornyn and state Attorney General Ken Paxton will advance to a runoff.

The pair will face off on May 26 in a race that has already drawn nearly $100 million in advertising, largely from Cornyn and his allies.

GOP Rep. Wesley Hunt's draw of 13% of the vote means none of the three major candidates was able to win a majority of the primary vote.

On the Democratic side, State Rep. James Talarico won the Senate nomination over Rep. Jasmine Crockett, NBC News projects, as the party seeks to put the traditionally Republican state in play this fall.

Voters in two Texas counties also faced confusion after new laws limited them to party-specific precinct polling sites. People who joined the line at polling sites after 7 p.m. local time cast provisional ballots, which the Texas Supreme Court has ordered to be kept separate. It's unclear whether those ballots will be counted.

Democrat Roy Cooper and Republican Michael Whatley will face off in North Carolina's Senate race.

Live Nation argues it's not a monopoly at DOJ antitrust trial

Live Nation, Ticketmaster's parent company, is pushing back against the government's claim that it is an "unlawful monopoly." The business has been the target of increased scrutiny by music fans who report frustrations with buying tickets through the platform.

The Department of Justice's 2024 lawsuit alleges that Live Nation has illegally dominated the live concert industry by monopolizing ticketing, concert booking, venues and promotions. DOJ attorney David Dahlquist pointed to a botched presale process for Taylor Swift's "The Eras" tour as evidence of one company controlling the market, describing the ticketing technology as "held together by duct tape."

Live Nation's attorney pushed back on the claim, saying it was the result of a cyber attack, and categorized the company as artist-centered.

The fishy beauty hack once again taking over TikTok

For beauty and fashion influencer Toni Bravo, the secret to glowing skin isn't a K-beauty serum or a triple-digit skin care device — it's a tin of sardines.

"Everyone wants a skin care routine until I bring up sardines. Do you want it or not?" Bravo told her 930,700 TikTok followers. "I've eaten sardines my entire life … so I've known the power, the beauty that is fish."

The concept of "eating your skin care"— specifically fatty fish like tinned sardines, salmon and mackerel — isn't new. Long embraced in wellness circles as a kind of "nature's Botox," sardines are rich in omega-3 fatty acids, high-quality protein, calcium, vitamins, selenium and iron. They have been linked to improving skin barrier function and reducing inflammatory responses, both of which can contribute to healthier-looking skin over time.

But the trend has once again taken hold on TikTok, where users are experimenting with "sardine diets" for everything from weight loss to clearer skin, while others are simply adding the salty snack to their routines after seeing the results — or at least the promise of them — on Bravo and other influencers.
