"Economists across a broad ideological spectrum argue that investments in scientific research — especially the kind of fundamental, early-stage research that is too risky to attract private investors — are among the most efficient uses of taxpayer dollars."
Tariffs get all the attention, but ask economists what they're really worried about and many will point to the Trump administration's cuts to federal support for the sciences, including canceling grants and revoking student visas.

Zelensky is a wartime leader watching his people suffer and die under Russian attacks every day. To be lectured and lied to by Trump and Vance, as they defend the war criminal dictator committing these atrocities, is unimaginable agony. An everlasting shame for America.
Trump has not uttered a critical word about Putin but he and his VP publicly belittled the leader of the nation Putin invaded.

I will never forget the photo of Zelenskyy’s face after he saw Russia’s war crimes in Bucha in 2022. He seemed to age years in an afternoon. Watching him constantly cross the world asking for aid that should have been thrown at him is one of the deepest shames of our age.
