politicalchic, your op is a mess. before you go handing out english lessons perhaps you should learn to post coherently and how to attribute quotes to their source.
that said, the majority of your post seems to be from an article on a conservative website that quotes a conservative organization. not exactly unbiased.
here is the published notice in the federal register

and here's a link to Michael Chertoff using the same powers in 2007.

and finally a link and quote of the pertinent part of the INA that grants the power to make such a change
INA Section 212(d)(3)(B)(i) said:
(B) (i) 20b/ 20c/ The Secretary of State, after consultation with the Attorney General and the Secretary of Homeland Security, or the Secretary of Homeland Security, after consultation with the Secretary of State and the Attorney General, may determine in such Secretary's sole unreviewable discretion that subsection (a)(3)(B) shall not apply with respect to an alien within the scope of that subsection or that subsection (a)(3)(B)(vi)(III) shall not apply to a group within the scope of that subsection, except that no such wa iver may be extended to an alien who is within the scope of subsection (a)(3)(B)(i)(II), no such waiver may be extended to an alien who is a member or representative of, has voluntarily and knowingly engaged in or endorsed or espoused or persuaded others to endorse or espouse or support terrorist activity on behalf of, or has voluntarily and knowingly received military-type training from a terrorist organization that is described in subclause (I) or (II) of subsection (a)(3)(B)(vi), and no such waiver may b e extended to a group that has engaged terrorist activity against the United States or another democratic country or that has purposefully engaged in a pattern or practice of terrorist activity that is directed at civilians. Such a determination shall neither prejudice the ability of the United States Government to commence criminal or civil proceedings involving a beneficiary of such a determination or any other person, nor create any substantive or procedural right or benefit for a beneficiary of such a d etermination or any other person. Notwithstanding any other provision of law (statutory or nonstatutory), including section 2241 of title 28, or any other habeas corpus provision, and sections 1361 and 1651 of such title, no court shall have jurisdiction to review such a determination or revocation except in a proceeding for review of a final order of removal pursuant to section 1252 of this title, and review shall be limited to the extent provided in section 1252(a)(2)(D). The Secretary of State may not ex ercise the discretion provided in this clause with respect to an alien at any time during which the alien is the subject of pending removal proceedings under section 1229a of this title.

so, do you have anything other than your biased source to back up your claim that this is an abuse of powers, illegal, unconstitutional, or in any way improper?
1. "The Obama administration has issued new exemptions to a law that bars certain asylum-seekers and refugees who provided “limited material support” to terrorists who are believed to pose no threat from the U.S.
The Department of Homeland Security and the State Department published the new exemptions Wednesday in the Federal Register to narrow a ban in the Immigration and Nationality Act excluding refugees and asylum seekers who had provided limited material support, no matter how minor, to terrorists.
“These exemptions cover five kinds of limited material support that have adversely and unfairly affected refugees and asylum seekers with no tangible connection to terrorism: material support that was insignificant in amount or provided incidentally in the course of everyday social, commercial, family or humanitarian interactions, or under significant pressure,” a DHS official explained to The Daily Caller."

2. "...do you have anything other than your biased source to back up your claim that this is an abuse of powers, illegal, unconstitutional, or in any way improper?"
