The government agrees that they cannot use your statements delivered in connection with a proffer against you in later court proceedings. This is separate from just saying, Hey, let's come in and talk about a plea deal. This is a specific written agreement whereby you provide valuable information. So could Trump try and pin this all on John Eastman and Rudy Giuliani? I don't know.
