GOP lawmakers call for ethics investigation of Castro's tweet on Trump donors

In a letter to House Ethics Committee Chairman Ted Deutch, D-Fla., and ranking member Rep. Kenny Marchant, R-Texas, the lawmakers accused Castro of “violating Rule XXIII of the Code of Official Conduct for publicly posting the names and workplaces of individual donors to” Trump.

“Posting a target list of private citizens simply for supporting his political opponent is anithetical to our principles and serves to suppress the free speech and free association rights of Americans,” the letter says.

Republicans Reps. Andy Biggs of Arizona, Matt Gaetz of Florida, Jody Hice of Georgia, Debbie Lesko of Arizona, Jeff Duncan of South Carolina, Randy Weber of Texas and Ted Budd of North Carolina all signed the letter.
