Expose media lies & hammer them publicly on said lies. Shoot, have them hammer themselves.
For example, AP is still(!) writing articles (that show up in almost every medium and large newspaper) that state that Trump intends to ban all Muslims from entering the US. Trump has never said or even implied this.
Any source or paper that does not publish a simple and direct front page retraction with the headline “We lied, vetted Muslim ok to enter” at least 1” tall, the same number of days the lie has been printed, is not allowed into press conferences, speeches, the press pool, etc., by Administration members including the President.
“vetted Muslims”
