Gas prices are up 50% since February Inflation is skyrocketing High diesel prices are raising the costs of shipping everyday goods And it's all because of Trump's illegal war with Iran.
Trump's illegal war is costing our country a lot more than "25 BILLION" in taxpayer dollars. The true cost includes the lives of 13 U.S. servicemembers, relationships with our allies, and costs here at home to skyrocket. All because Trump "had a feeling"...
Hegseth says he’s ordering a “real science” study on women in combat arms. But this isn’t about discovery—it’s about doubt. Women in combat have already proven themselves. The real question is whether this regime will follow the facts or cherry-pick findings to fit its agenda.
Every day, this regime works to undermine our laws as they abuse their power to push their corrupt, cruel, and chaotic agenda. But the rule of law is non-negotiable. And today, on Law Day, it's important that we make that clearer than ever.
I asked Pete Hegseth if he's laying the groundwork to reverse the policy on women in combat. He didn't say no, then began rambling about "the highest male standard." His overt misogyny is an insult to the sacrifice of the MILLIONS of women who serve and have served our country.
Fuel costs are skyrocketing because of Trump's illegal war in Iran. This week, I sat down with Kaua'i Island Utility Cooperative to discuss how to counteract these rising fuel costs while continuing to increase the use of more affordable, reliable, renewable power in our state.
In functionally overturning the last enforceable section of the Voting Rights Act, the Supreme Court has once again put the interests of Republicans and their billionaire buddies before the voting rights of millions of Americans.
Is slavery a partisan ideology? It's a yes or no question. But Sec. Burgum would not answer. He refused to answer in a Senate hearing, yet has happily used "partisan ideology" as a pretext to scrub the history of slavery from our national parks. Unacceptable.
I recently got to talk to students from Kaʻelepulu and Kāneʻohe Elementary during their visit to D.C.! From discussing KPop Demon Hunters to answering questions about my job in the Senate, it was refreshing to have these young, excited, and bright individuals on Capitol Hill!
Trump's promise to "end inflation" was total BS. New reporting shows Americans have spent over $2,300 MORE on groceries, housing and energy costs due to needless inflation under Trump. $2,300 MORE. Because of his illegal tariffs, unauthorized war and terrible economic policies.
Americans have paid $16 BILLION more at the pump since Trump began his illegal war with Iran. And that doesn't include the BILLIONS in U.S. tax dollars spent EVERY DAY on the war. Americans voted for lower costs, not a war projected to cost our country $1 trillion.
It's hard not to be in awe of our beautiful planet after seeing the photos taken by Artemis II on their recent mission. Today, on Earth Day, as this regime attacks environmental protections, let these photos be a reminder of the importance of protecting our only home — Earth.
