Matter of Velazquez-Herrera, 24 I. & N. Dec. 503, ___ (BIA May 20, 2008) ("In seeking to identify the "federal policies" underlying section 237(a)(2)(E)(i), we find it significant that the provision was enacted pursuant to the IIRIRA as part of an aggressive legislative movement to expand the criminal grounds of deportability in general and to create a "comprehensive statutory scheme to cover crimes against children" in particular. Matter of Rodriguez-Rodriguez, supra, at 994. In addition to the changes brought about through the enactment of section 237(a)(2)(E)(i), for example, Congress also expanded the aggravated felony definition to encompass offenses involving the "sexual abuse of a minor." See IIRIRA 321(a)(1), 110 Stat. at 3009-627 (amending section 101(a)(43)(A) of the Act); see also United States v. Corona-Sanchez, 234 F.3d 449, 454 (9th Cir. 2000) (referring to the IIRIRA as "expansive legislation" and recognizing, in the aggravated felony context, that the statute was "intended to sweep a broad range of offenses" into the grounds of deportability); H.R. Rep. No. 104-828, at 505-06 (1996) (Conf. Rep.) (Joint Explanatory Statement of the Committee of Conference). Prior to the enactment of the IIRIRA, the immigration laws did not subject aliens convicted of crimes against children to any particular disadvantage vis-a-vis other criminal aliens. By enacting section 237(a)(2)(E)(i) of the Act and other provisions augmenting the aggravated felony definition, however, Congress clearly intended to single out those who have been convicted of maltreating or preying upon children. In view of the fact that section 237(a)(2)(E)(i) of the Act is the product of a significant expansion of the grounds of deportability and was aimed at facilitating the removal of child abusers in particular, it is our view that the term "crime of child abuse" should be interpreted broadly in this context.").
