You’re correct. But FWIW I didn’t write it.

The audacity and success of the Collins-Murkowski political strategy of “I was bamboozled and actually oppose every vote I have ever made” never ceases to astound me.

A post claimed an Iowa shark attack happened. It was fake, but a shark bite did happen before. A shark bite in Iowa fits the definition of a fish out of water. But that didn't stop a fake news article about a shark bite from spreading.

There were no Iowa shark attacks — this year

EPA eliminates its scientific research arm The move to dismantle the Office of Research and Development comes as Trump officials cut the agency’s total staff by 23 percent.

EPA eliminates its scientific research arm The move to dismantle the Office of Research and Development comes as Trump officials cut the agency’s total staff by 23 percent.

“The move to eliminate the Office of Research and Development … is part of a push to cut 23 percent of the agency’s staff. Its work, which often underpinned stricter federal regulations, was criticized by chemical manufacturers and other industries.”

Trump’s EPA just eliminated its entire research arm—the “heart and brain” of the agency—and is laying off 3,700 workers.

That’s 1,155 scientists, chemists, and biologists gone.
Less science. More pollution.

This isn’t reform. It’s sabotage.

EPA eliminates research and development office, begins layoffs The Environmental Protection Agency said Friday it is eliminating its research and development arm and reducing agency staff by thousands of employees.

Total staffing at EPA will go down to 12,448, a reduction of more than 3,700 employees, or nearly 23%, from staffing levels in January when Trump took office, the agency said.

The Senate just posted the report language of its FY26 science appropriations bill. This text lays out what they want done and carries the force of law if it is included in the final spending bill.

It's a line-by-line refutation of Trump's proposed budget for NASA and NOAA.

FBI agents were told to "flag" any Epstein records that mentioned Donald Trump.... Sen. Durbin has asked the Justice Department + FBI to explain what his office called “apparent discrepancies” regarding handling of the Epstein files. www.cnbc.com/2025/07/18/t...
