Back to Square One
After a defendant, with the courts permission, withdraws a guilty plea, the case normally reverts to the point before the original plea. The defense can hammer out another deal with the prosecution or go to trial. If the reason for the withdrawal undermines the prosecutions case (as in the instance of newly discovered evidence of innocence), the judge might even dismiss the charges. But withdrawing a plea doesnt always end happily: Theres typically no guarantee that the defendant wont receive a harsher sentence if convicted (again).

This may be why Gen Flynn is maintaining his plea.

Judge Sullivan: “This is a very. Serious. Offense. A high-ranking senior official of the government making false statements to the FBI while on the physical premises of the White House.
Judge: Is Mr. Flynn still cooperating with and providing assistance to the government?
SCO’s Brandon Van Grack hesitates. It remains a possibility,” he says, that Flynn will cooperate further.

Sullivan describes Flynn’s crime as a “very serious offense” — a high ranking government official lying to the FBI, and doing it “while on the physical premises of the White House.”
Mueller prosecutor Brandon van Grack haltingly tells Sullivan it is a “possibility” that Flynn is still cooperating with the special counsel’s office.
