Families in Gaza are starving while the food they need is sitting at the border. But @WFP hasn't been able to get new aid in since 2 March. If we wait for famine to be officially confirmed, it will be TOO LATE. We need access. We need a ceasefire. We need to move NOW.

The Supreme Court has said that Trump is required to facilitate - which means, as Judge Wilkinson said in his opinion yesterday, take active steps to make happen - Garcia's return. And instead the White House is publicly, and mockingly, saying "He's never coming back."

This is terrible, terrible, terrible news for the American people and the tax system. The only winners are high-cost tax preparers. When fully built out, Direct File would've saved taxpayers ~$20B annually. apnews.com/article/irs-direc…

"The government is asserting a right to stash away residents of this country in foreign prisons without the... due process that is the foundation of our constitutional order... it claims in essence that because it has rid itself of custody that there is nothing that can be done."
Excellent Fourth Circuit opinion (Judge Wilkinson writing) rejecting the government's attempts at evasion in the Abrego Garcia case. storage.courtlistener.com/re…

Even if one thought these were all good ideas, it is entirely inappropriate for the federal government to try to impose them on a private university
BREAKING: The government has delivered its demands to Columbia, including: -Placing discipline under the president -A mask ban -Adopting IHRA or similar -“Placing the Middle East, South Asian, and African Studies department under academic receivership” -Admissions reform
