Let me know if you find a valid link to Gowdy’s statements.
There isn’t one; turns out that twttr account is not the real Sidney Powell.
I have been through his Twitter and there is nothing there. I respectfully submit that Rita may be mistaken and following a fake "Sydney" channel. I cannot find any evidence of a tweet from Gowdy, even in the fake "Sydney Powell" telegram channel. I found a breathless 'list of everyone in the black eye club' post on that Telegram channel, but nothing else. (I believe the Powell site that Rita is referencing is not the real Sidney Powell channel, as her name is not spelled correctly.)
There are a couple of Ted Cruz items that are forwarded there, nothing from Trey Gowdy though. Here's the channel if you want to look for youerself. Note the zero in the name, to differentiate from the real Powell channel.
