Someone is dying in ICE detention EVERY WEEK. And this regime is closing one of the offices responsible for investigating misconduct and abuse in the immigration detention system. ICE needs guardrails — yet this regime continues to let ICE's cruelty go completely unchecked.

Senator Mazie K. Hirono@hirono.senate.govMay 12(source)

Tanning beds and fruit-flavored vapes somehow fit into this regime's "Make America Healthy Again" agenda, but vaccines, Tylenol, and anti-depressants are the problem?

Senator Mazie K. Hirono@hirono.senate.govMay 12(source)

A great day to be a bow! 🌈 Congrats to the UH Men's Volleyball team for bringing home the NCAA Men's Volleyball trophy last night! You've made our state so proud!

Senator Mazie K. Hirono@hirono.senate.govMay 11(source)

Trump's regime is calling this the "Golden Age" for farmers. Higher fertilizer costs = lower harvest rates Low harvest rates = less food Less food = higher costs for Americans There is nothing "golden" about high costs and U.S. farmers' inability to grow food for our country.

Senator Mazie K. Hirono@hirono.senate.govMay 7(source)

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.

Senator Mazie K. Hirono@hirono.senate.govMay 6(source)

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"...

Senator Mazie K. Hirono@hirono.senate.govMay 6(source)

Millions of Americans — our neighbors, our loved ones, our friends — are going without health care coverage because Republicans prioritized tax breaks for billionaires over the well-being of our nation. www.nytimes.com/2026/05/01/b...

Since Congress Let Obamacare Subsidies Expire, Millions Are Dropping Coverage

Senator Mazie K. Hirono@hirono.senate.govMay 5(source)

This regime can attack DEI all it wants, but the through line of America is — and always will be — diversity.

Senator Mazie K. Hirono@hirono.senate.govMay 5(source)

Good. Because mifepristone is SAFE. Anyone trying to stop its distribution isn't protecting women's safety — they're controlling women's bodies. And they're willing to put patients at risk to do so. apnews.com/article/abor...

Supreme Court restores access to abortion pill mifepristone through telehealth, mail and pharmacies

The Supreme Court has restored broad access to the abortion pill mifepristone, blocking a ruling that had threatened to upend one of the main ways abortion is provided across the nation.

Senator Mazie K. Hirono@hirono.senate.govMay 4(source)

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.

Senator Mazie K. Hirono@hirono.senate.govMay 1(source)

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.

Senator Mazie K. Hirono@hirono.senate.govMay 1(source)

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.

Senator Mazie K. Hirono@hirono.senate.govMay 1(source)

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.

Senator Mazie K. Hirono@hirono.senate.govApr 29(source)

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.

Senator Mazie K. Hirono@hirono.senate.govApr 29(source)

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.

Senator Mazie K. Hirono@hirono.senate.govApr 28(source)

Tens of thousands of people are going to die because this regime prioritizes conspiracy theories over science and years of proven research. This lethal decision can't even be blamed on incompetence. This decision is just plain evil and cruel. www.politico.com/news/2026/04...

RFK Jr. is holding up $600M in vaccines for poor countries

The distributor of the shots said it would cost tens of thousands of lives.

Senator Mazie K. Hirono@hirono.senate.govApr 28(source)

Donald Trump will do anything he can to make the American people pay more for the things they need.

Senator Mazie K. Hirono@hirono.senate.govApr 28(source)

In Hawaii, gas prices are up over 28%. That means people in Hawaii are paying AT LEAST $45 MORE a month just on gas alone. The reason? Trump's illegal war in Iran.

Senator Mazie K. Hirono@hirono.senate.govApr 27(source)

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!

Senator Mazie K. Hirono@hirono.senate.govApr 24(source)

Pete Hegseth is weakening our military by prioritizing bigotry and sexism over merit, skills, and experience — it’s pathetic, dangerous, and a disgusting misuse of power. www.nytimes.com/2026/03/27/u...
