SUMMARY ORDER
Fayiz Halabi, a native and citizen of Israel, seeks review of an October 29, 2007 order of the BIA, affirming the January 24, 2005 decision of Immigration Judge (“IJ”) John B. Reid, denying his application for withholding of removal and relief under the Convention Against Torture (“CAT”). In re Fayiz Halabi, No. [ AXX XXX XXX ] (B.I.A. Oct. 29, 2007), aff'g No. [ AXX XXX XXX ] (Immig. Ct. Batavia Jan. 24, 2005). We assume the parties’ familiarity with the underlying facts and procedural history in this case.
As an initial matter, although Halabi is challenging the denial of relief in “withholding-only” proceedings, as opposed to an actual removal order, we nevertheless have jurisdiction under 8 U.S.C. § 1252(a)(1) because the denial of relief in these circumstances is the functional equivalent of a removal order. See Kanacevic v. INS, 448 F.3d 129, 134 (2d Cir.2006).
In this case, we need not review the merits of the agency’s denial of -withholding of removal and CAT relief, because, as the Government argues, Halabi waives any challenge to those determinations.1 Issues not sufficiently argued in the briefs are considered waived and normally will not be addressed on appeal. Yueqing Zhang v. Gonzales, 426 F.3d 540, 541 n. 1, 545 n. 7 (2d Cir.2005). Aside from his conclusory assertions that the IJ erred in declining to grant him withholding of removal, Halabi does not challenge the IJ’s inconsistency findings or the IJ's determination that he failed to demonstrate a nexus between any harm suffered or likely to be suffered and a protected ground. Moreover, the IJ’s findings were, in any event, supported by *867the record. Indeed, the IJ’s adverse credibility finding was properly based on substantial omissions and inconsistencies involving the heart of Halabi’s claim. See Cheng Tong Wang v. Gonzales, 449 F.3d 451, 453-54 (2d Cir.2006); see also Majidi v. Gonzales, 430 F.3d 77, 79-80 (2d Cir.2005)
Finally, because Halabi has limited his assertion of error as to the agency’s denial of CAT relief to “only a single conelusory sentence,” we deem any such challenge waived. See Yueqing Zhang, 426 F.3d at 545 n. 7.
For the foregoing reasons, the petition for review is DENIED. As we have completed our review, the pending motion for a stay of removal in this petition is DENIED as moot.
