v. Powell, 767 F.3d 1026, 1029-30 (10th Cir. 2014) (quotations omitted). 3. Analysis The government concedes on appeal that the district court committed an error that is plain when it submitted the issue of drug quantity to the jury without the required beyond-a-reasonable-doubt standard. The government nevertheless argues Johnson is not entitled to relief because the error did not affect her substantial rights and did not affect the .fairness, integrity, or public reputation of judicial proceedings. In so arguing, the government asserts the evidence as to drug quantity is overwhelming. Notwithstanding the government’s assertions, this court concludes Johnson has demonstrated the jury’s drug quantity determination is not supported by overwhelming evidence. See Wright, 848 F.3d at 1278 (<HOLDING>). Thus, the district court’s Alleyne error
holding the burden is on the defendant to demonstrate the error satisfies each prong of the plain error test recognizing that the defendant bears the burden of establishing that plain error was prejudicial holding that where the appellant has failed to demonstrate error the court is not required to search the record for an error holding that the defendant necessarily bears the burden of satisfying the third prong of the plain error test holding that it is the burden of the party who failed to preserve his argument to demonstrate plain error
