Wrong.
From http://checkyourfact.com/2023/03/08/fact-check-desantis-mar-a-lago-raid/ :
The claim is false. There are no credible news reports suggesting DeSantis had advanced knowledge of the FBI’s Aug. 8, 2022 raid on Mar-a-Lago. Likewise, no mention of the claim appears on the Republican governor’s website or his verified social media accounts. In addition, the DOJ has not publicly addressed the purported claim.
A keyword search reveals the claim stems from a Mar. 3 article published on the website “Real Raw News.” A disclaimer included on the site’s “About Us” page indicates it contains “humor, parody, and satire.”
What has Ron said about it? Has anyone asked him?
