(CNSNews.com) – Senator Lindsey Graham (R-S.C.) took to Twitter Friday to attack President Obama’s move to grant effective amnesty to young illegal immigrants:

He was among the first lawmakers to react to the surprise announcement.

“President Obama’s attempt to go around Congress and the American people is at best unwise and possibly illegal,” he tweeted.

Graham, a former Air Force prosecutor, said the move, “regardless of motivation, will entice people to break our laws.”

While Homeland Security Secretary Janet Napolitano insisted the program “is not amnesty,” other senior administration officials admitted that the program will stop illegal immigrants from being deported, even if a judge has already ordered it.
