The Florida Bar has opened an ethics investigation of U.S. Rep. Matt Gaetz, a Fort Walton Beach attorney, based on a tweet targeting ex-Trump attorney Michael Cohen and seen by some as witness tampering.

Although the bar would not confirm the nature of the complaints, Gaetz fired off the controversial tweet Tuesday, prompting widespread condemnation and spawning a copy-and-paste Twitter campaign. The Twitter posters called on other users to file a complaint with the Florida Bar in order to have Gaetz disbarred for witness tampering.
