While I am still gathering information about Mahmoud Khalil’s case, detaining someone and threatening to revoke their legal immigration status without evidence of a crime—simply because you disagree with their beliefs—is a gross violation of the First Amendment.

Elon Musk should not have access to private citizens’ personal data that they have shared with the federal government. I teamed up with Rep. Stevens to introduce the Taxpayer Data Protection Act, legislation that ensures US private citizens’ data is not subject to reckless and unlawful interference.
🚨 NEWS: I partnered with Reps. Jan Schakowsky and Jerry Nadler to lead 73 House Democrats in demanding that the Department of Justice fully enforce the FACE Act and ensure women and health care providers are not threatened, harassed, or abused while entering reproductive health facilities.
Today, I visited the O'Hare International Airport Control Tower with Chicago air traffic controllers. These are hardworking and dedicated civil servants focused on keeping our skies safe. We owe them our gratitude.
Banks that operate without a Chief Risk Officer jeopardize American’s hard-earned savings. That’s why I introduced the Chief Risk Officer Enforcement and Accountability Act, legislation to require large banks to employ a Chief Risk Officer and to increase public transparency. Read more:

Republicans on the House Financial Services Committee repeatedly attacked my amendment to stop Elon Musk's illegal access to Americans' private data.
They didn't attack the policy of my amendment but railed against it as partisan.
It should not be partisan to defend our Constitution.
You can change the laws of the United States, but you can't change the laws of nature.
Limiting the EPA's ability to regulate greenhouse gas emissions would have lasting and devastating impacts on our planet.
President Trump lied to the American people during his address on Tuesday night. Here’s the truth:
So I return to my request. How do you define those words?

Those questions about liberty and markets are the essence of our Republic. Within that healthy and necessary debate, there is ample room for every article that has ever appeared on the Washington Post opinion page. And yet you clearly believe that the scope of that debate has been too broad.
And so, the question of what constitutes a commitment to free markets also comes down to a question of regulation. Like liberty, a commitment to free markets has to be more than a regulation-free anarchy where whoever gets the most stuff the fastest sets all the rules.
Per Adam Smith, the invisible hand of capitalism only exists when there are no barriers to entry or exit and transparent information that allows for robust competition. But, as you know as well as anyone, no business really wants that.
But what then do you make of a regulated utility monopoly that faces no competition but keeps the lights on in exchange for prices set by a local government agency?
And what of free markets? Surely you would agree that a mobster’s protection racket is not a free market, even if money is exchanged for services.
What rights to liberty apply to non-citizens on our shores? What rights to self-determination and personal liberty should we insist on for Ukrainians, Taiwanese, Palestinians… or Cherokee?
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.
