He can’t. In this chess game, if he did that, the Rats would immediately call for impeachment, and enough GOPe RINOs, led by McCain, would go along to make it stick.
Trump has a better option to end this instantly, if, as we all assume, he is completely innocent.
First, Trump should issue a blanket pardon to anyone in his circle who might be indicted on any charge.
Second, Trump, as Chief Executive Officer of the Department of Justice, should order the attorney General to release 100% of the evidence that has been gathered on the Russian election issue, and release 100% of the intra-department correspondence related to the Russian issue.
Comey & Friends would go berserk - because there is no evidence, and because their internal correspondence would destroy their professional reputations for all time.
