I'm giving him the benefit of your doubt.

CNN issued a correction after the network inaccurately asserted that President Donald Trump “falsely claimed” the Biden administration spent $8 million to make mice transgender.

During his joint address to Congress on Tuesday, Trump cited several examples of “appalling waste” he had cut, including $8.2 million in NIH-funded studies on “gender-affirming” hormone treatments mice. CNN’s Deidre McPhillips initially tried to dispute the claim, arguing only about $500,000 had been allocated for similar research in monkeys — she was later forced to issue a correction after the White House proved CNN’s “fact check” inaccurate in a statement.

And there it is now ! Right on time.

That "fact" check got corrected. They made trans mice to study the affects of hormone therapy.
