For Senator Angela Alsobrooks : I’m a retired USAF vet in Rockville MD. Mahmoud Khalil was improperly detained under a Cold War-era law. His wife is 8 mos. pregnant. His arrest and detainment without charge violates the Constitution that you and I both swore to defend. Please speak out.

For Senator Senator Chris Van Hollen and Rep. Jamie Raskin: I’m retired USAF in Rockville. Mahmoud Khalil is being detained without his Due Process rights. This violates the Constitution we all swore to defend. Please speak out.

Thank you, Rep. Jamie Raskin, for being a constitutional conscience in Congress. The public needs transparency and leaders unafraid to speak truth to power. #ProtectTheConstitution Oversight Dems Senate Judiciary Democrats 🇺🇸 The Lincoln Project

Listing my current priorities for my representatives: Support Ukraine (and show them respect!) 🇺🇦. Defend the Constitution 📜. Support the Balance of Powers. ⚖ #ConstitutionFirst #StandWithUkraine @sen_alsobrooks Senator Chris Van Hollen Rep. Jamie Raskin

Disgusting. Rep. James Comer (R-KY) of Oversight, in an incredibly rude letter, rejects funding for Dem Reps Congressman Robert Garcia and Congressman Maxwell Alejandro Frost to go check on Abrego Garcia. That he’s not approving the funding, fine, but to reject it with this much mean-spirited snark and lies

Good to see that the needle is moving in the right direction! ⁦Senator Chris Van Hollen⁩ ⁦Congressman Robert Garcia⁩ ⁦Rep. Jamie Raskin⁩ washingtonpost.com/politics/2025/…
