So let’s set out to maximize the greatest liberty for the greatest number. How should we structure our society to ensure that outcome? How much should one person be allowed to reduce our collective liberty before we put them in prison to take away their personal liberty?
Surely you don’t mean the purely individual definition of personal liberty, where we are all free to do whatever we want. Our founders were more sophisticated than that, and after proclaiming our right to liberty as a self-evident truth, went on to create a representative democracy - not an anarchy.
A few people have asked, so sharing the text of the letter here: Mr. Bezos, In light of your recent announcement that the Washington Post opinion page will only publish articles that support personal liberty and free markets, I’d like to ask for a clarification: How do you define those terms?
Schools should be a safe haven for children. It’s more important than ever that we equip schools with the tools they need to protect students from sexual harassment and abuse. I partnered up with Rep. Frankel and Rep. Hayes to introduce the Stop Sexual Harassment in K-12 Act. Read more:
Jeff Bezos recently said the Washington Post would only publish op-eds supporting "personal liberties" & "the free market." In response, I submitted a letter asking Mr. Bezos to define his terms. I'm releasing the letter in light of WaPo’s refusal to respond. After all, democracy dies in darkness.
Last week, I led 107 House Democrats in a letter to Department of Energy Secretary Chris Wright demanding he end the illegal firing of public servants, including those responsible for managing the United States’ nuclear weapons arsenal. Read the letter: casten.house.gov/media/press-...
NEWS: I joined 152 House Dems in urging the Social Security Administration to halt the Trump-Musk plan to shutter field offices & reduce its workforce. The world's richest man, who recently called Social Security a Ponzi scheme, has no business stripping Americans of their earned benefits.
Over the weekend, I hosted a seniors-focused community meeting in Westmont. I shared updates on how I’m working to protect necessary federal services, like Medicare and Medicaid.
This is disgraceful. There was only one person in the Oval Office willing to stand up for democracy and against Putin, and it wasn’t the President or Vice President of the United States.
A meeting between President Trump and Ukrainian President Volodymyr Zelenskyy grew contentious, with Trump telling Zelenskyy that "you're not acting at all thankful" for U.S. support.
Last month, I spent time at the National Air Traffic Control Center in Illinois. Air traffic controllers deserve access to mental health care when they need it. I'm working on bipartisan legislation to ensure that aviators can get the help they need.
Yesterday, on the House Floor, I shared the story of a federal scientist who Donald Trump and Elon Musk fired. By halting the work of our federal researchers, we are crippling our nation’s ability to innovate, adapt, and maintain our status as a world leader in science.
Last week, I partnered with Rep. Robin Kelly to introduce the Gun Trafficker Detection Act. This legislation would help end the flow of illegal guns into Illinois by requiring gun owners to report if their gun is lost or stolen within 24 hours. Read more: casten.house.gov/media/press-...
Imagine being so terrified of Elon Musk and Donald Trump that the only way you are willing to advocate for the HUMANE treatment of federal public servants is to do so *privately*.
