Can a defendant who has secured the benefits of a plea agreement, knowingly and voluntarily waived their right to appeal their sentence?

This argument is without merit. To begin with, Andino waived her right to appeal her 18-year sentence in her plea agreement. See United States v. Maher, 108 F.3d 1513, 1531 (2d Cir.1997) ("In no circumstance ... may a defendant, who has secured the benefits of a plea agreement and knowingly and voluntarily waived the right to appeal a certain sentence, then appeal the merits of a sentence conforming to the agreement.") (alteration in original) (quoting United States v. Salcido-Contreras, 990 F.2d 51, 53 (2d Cir.1993) (per curiam)). We would therefore be justified in ending analysis here.
