October is National Book Month. I met with the team at the Tri-Town YMCA in Villa Park and dropped off books from the Library of Congress Surplus Books Program for young readers in our community.

Delayed tax returns can be extremely frustrating. When a constituent in Tinley Park was having trouble receiving their 2024 tax return, they reached out to my office for help. My team worked with the constituent and the Taxpayer Advocate Service (TAS) to address a discrepancy with the IRS and helped facilitate the release of the tax return. Are you having trouble with a federal agency? Reach out to my office and let us help. casten.house.gov/services/he…

Slashing rural healthcare, picking tariff wars that decimate US soy exports as you bail out Argentinian producers & blocking wind energy are all bad politics in IA. Which is only surprising if you also didn't notice that Iran controls the Strait of Hormuz. nytimes.com/2026/10/22/us/po…

No swords or strings, @elonmusk. I'd just like you to explain to Congress and the American people why DOGE failed so miserably and why you then lied about the savings. Will you commit to testifying under oath to explain?
Live by the sword, die by the sword. Those who pick fights with me should understand that I will find out who is really pulling the strings and come for them, not just their puppets …

6. At the end of the day the Trumps and their spouses are bullies and grifters. The people around them are weak-willed sycophants. Neither succeeds without the other and both are equally responsible for this moment. Our country can't afford let either of them off the hook. /fin

Harry Truman left the White House with nothing but a $113 a month Army pension.  Donald Trump made at least $2.2 billion in his first year back in office. He pulled in $1.4 billion from crypto alone in 2025. Companies backed by his sons have landed billions in Pentagon contracts. And he made thousands of stock trades in the first three months of this year, including in companies his own administration regulates. The grift never stops. Meanwhile, working families are scraping by to cover gas, groceries and electric bills that keep climbing. They haven't seen a dime of Trump's windfall. They're the ones paying for it. If you're fed up with a president who treats the White House like a personal ATM while Americans struggle to hold on, fight back by voting on November 3rd. #TrumpsCrimesOnYourDime

LGBTQIA+ rights are human rights. I proudly stand with LGBTQIA+ Americans in IL-06 and across the country, and I’m grateful to receive a 100% on @HRC's Congressional Scorecard for my record of fighting back against attacks on equality.

If you want to help democracy, make sure a great member of Congress comes back, blow a hole in Florida's gerrymander AND make sure Trump wastes millions of dollars... throw some $ Jared Moskowitz' way in these final weeks. It's a win/win all around. secure.actblue.com/donate/ja…

His default mode is aggression. Especially with women.
Trump: We were in the midst of negotiating and a lot of stupid people said why aren’t you putting Russian sanctions— Collins: But you said you didn’t give anything for his release Trump: If I didn’t do that, you wouldn’t have him coming back. Collins: So you did give something. Trump: You don’t know anything. You’re fake news CNN. Collins: You’re saying you lifted the sanctions in exchange for his release? Trump: You don’t know what you’re talking about. You’re a low IQ person. You’re a dummy.
