Trump dragged us into a war with Iran with no idea what he was doing. We deserve answers about why he got us in this mess, but this Administration has none to give.

It was clear from the beginning that the situation on the USS Lincoln needed to be taken seriously. Instead of being honest about it and supporting our servicemembers, Trump and Hegseth denied and minimized what was happening. Failed leadership.
8 service members assigned to the USS Abraham Lincoln carrier group have attempted suicide during their extended deployment. The crew has endured severe supply shortages, lack of basic hygiene products, and poor-quality rations.

Americans are tired of waiting on Washington to take action on AI. So am I. It's why I'm introducing my bill to invest in workers by making Big Tech pay its fair share.

.@BillHillAK is as Alaska as it gets. He’s an independent leader, fisherman, and educator who’s running to be a fighter for working families. He’s the right person to be Alaska’s next representative in Congress.

.@Teresa4Nevada is a social worker and a leader in the Nevada legislature who’s always fought for her community. She’s spent her career delivering results for Nevadans, and she’s ready to do the same in Congress representing #NV02.

From lowering health care costs to fighting corporate monopolies, @TomPerriello has always sided with the people over the powerful. Now he’s running for Congress in #VA05 to be a leader Virginia families can count on.

Election Day is 6 weeks away, and leaders across the country are stepping up to flip key districts. These candidates are running to lower costs, take on the corruption in Washington, and fight for working families. I’m proud to endorse them.

While regular families count every dollar at the grocery store, billionaires are paying lower tax rates than the people ringing them up. Politicians made that choice. They work for the wealthy instead of you. I want to change who Washington works for.

State run media, state owned enterprises, prosecuting political opponents, gifts from foreign countries, selling pardons, massive amounts of money flowing into the President’s bank account, and banners with his head plastered on government buildings. NONE OF THIS IS NORMAL.

Trump promised lower costs. Instead, diesel just hit an all-time high because of his war with Iran, and families are paying hundreds more this year on groceries and everything else. Arizonans shouldn't have to foot the bill for his reckless decisions.

It was great to be out in Ohio with my friend @SherrodBrown. Folks are fed up with Washington and this administration's corruption. It's why we need him in the Senate to continue his fight for working people.

No one works harder to protect Arizonans than @KrisMayes, whether it’s going after criminals, taking on corporations that are price-gouging families, or standing up for our state. I’m proud to call her my AG.

Trump doesn't care about rising gas prices, because it doesn’t affect him or his rich friends. But for families trying to afford rent and groceries, it's everything.

Mr. Secretary, I can send you an aircraft propulsion textbook if you’d like. What you are suggesting is not real. You need to crack open a book.
RFK Jr: "We are also looking at chemtrails"
Community note
RFK Jr. referred to "chemtrails," a conspiracy theory alleging secret chemical spraying by aircraft. No evidence supports this; trails are condensation (contrails) and a 2016 peer-reviewed survey of 77 atmospheric experts found 76 had seen none for such programs. epa.gov/regulations-em… iopscience.iop.org/article/10.108… statnews.com/2026/09/17/rfk…

Folks in Georgia are lucky to have a fighter like @Ossoff who is standing up to this Administration’s corruption and fighting to lower costs for families. And after talking to so many of them, I know they’ll do everything they can to re-elect him and help us take back the Senate.
