Today I offered a motion to help ensure Elon Musk no longer has unlawful access to Federal Government systems and the private, sensitive data of taxpaying Americans. All but one House Republican voted No and defeated my motion, choosing cowardice over patriotism.

This fight isn't over, but a bully is always counting on folks being unwilling to stand up. I'm standing up to Elon Musk and for the American people.

Second, I led 154 House Democrats in a letter to Treasury Secretary Bessent demanding answers about the extent of Musk's access to data and ability to stop federal payments to programs like SNAP, Medicaid, and Social Security. (3/4) casten.house.gov/media/press-...

First, in coordination with Democratic Leader Hakeem Jeffries, Congresswoman Haley Stevens and I introduced the Taxpayer Data Protection Act, landmark legislation from House Democrats to ensure your data is not subject to reckless and unlawful interference. (2/4) casten.house.gov/media/press-...

🚨NEWS: Tomorrow at 12pm CT, I'm hosting a telephone town hall to discuss the first few weeks of the Trump Administration and Elon Musk's unprecedented access to US citizens' personal data and federal disbursement systems.

Rep. Sean Casten@casten.house.govFeb 5(source)

Fascism survives so long as the evil at the top is supported by cowards below. Is any Republican in Congress willing to stand against Elon Musk and for the American People? Or will they sit in cowardly complicity with the evil of their leaders?

Rep. Sean Casten@casten.house.govFeb 4(source)

Illinois imported over $18 billion in goods from Mexico in 2023, including $163 million in agricultural products that feed our communities. Trump’s senseless tariffs will result in higher prices for consumers.

Rep. Sean Casten@casten.house.govFeb 4(source)

Elon Musk’s access to Treasury payment systems threatens Americans’ national and economic security. As a member of the Financial Services Committee, which oversees the Treasury Department, I'll use all available tools to address this egregious power grab. I'll share updates soon.

Americans deserve a national energy policy that prioritizes the needs of consumers over the wants of energy companies. Last week, I convened experts and stakeholders to discuss how we can fight Trump's efforts to limit access to cleaner, cheaper energy. www.chicagotribune.com/2025/01/31/i...

The Trump Administration’s funding freeze would have disastrous consequences for Illinois. I convened a roundtable of local leaders, stakeholders, and advocates to discuss how a federal funding freeze would impact Illinoisans’ access to cleaner, cheaper energy.

Earlier this week, I connected with Senior Trustee Anthony Puccio and staff members of the Village of Lombard. I look forward to working together throughout the 119th Congress!

As I said yesterday, you cannot take the Trump Administration at their word. You have to watch what they do. Do not let them fool you into thinking this is the end of their assault on Medicaid, SNAP, and other essential services.
