Here is more from The Hill:
President Trump on Monday lashed out at the Center for American Progress (CAP), a liberal think tank, after it released a report last month suggesting the National Guard deployments failed to reduce violent crime.
“Chandler Hall, representing, on Television, the foolish Center for American Lack of Progress, stated that adding the National Guard to Cities, including our now Great Again, Washington, D.C., had ‘NO impact on Crime,'” Trump wrote on Truth Social, referring to the report’s author. “How crazy is that. Hall was met with furious dissent.”
Trump called the research “another Radical Left SCAM, as are the people who fund this gaggle of Lunatics, including George Soros, Bill and Melinda Gates, Google, Apple, Visa, Goldman Sachs, Citigroup, Wells Fargo, Bank of America, Walmart, Toyota, T-Mobile, and NBC Universal.”
He added that he will file a lawsuit and add “some of the contributors to this Fake Organization.”
The Washington Post Editorial Board called Trump's attack on CAP "an affront to the First Amendment."
