This program rightly had bipartisan support. It was a humane way to protect the best & brightest kids who are investing their future in America. https://www.presidentsalliance.org/press/u-s-phases-out-needed-special-student-relief-ssr-that-protects-international-students-from-crisis-countries/04 May 2026 13:12 +0000at://did:plc:skf244z64dfa5yvynksq65ij/app.bsky.feed.post/3mkzqrgeses2fhttps://bsky.app/profile/mclem.org/post/3mkzktfget22rShame on every last person in public office who lacks the minimal integrity to state the most basic facts. Disemboweling our Constitution, by denying that it was written in English and that English words have meanings, is the very opposite of “Conservative”. It will harm ALL Americans.

Deals are nothing, a scrawl on tissue paper that is only good until the deal’s off. Shattering our institutions, rules, and norms in favor of ‘deals’ is trading a bag of diamonds for a bag of Doritos. https://www.nytimes.com/live/2026/05/03/us/trump-news-iran?unlocked_article_code=1.f1A.RFcX.SpwhzTzK-Rg3&smid=nytcore-ios-share04 May 2026 02:24 +0000at://did:plc:skf244z64dfa5yvynksq65ij/app.bsky.feed.post/3mkymki66yc22https://bsky.app/profile/mclem.org/post/3mkvym6ua6c2jThis statement by the President of the United States calls for several leaders of the opposition party to be executed.
