Obama letting some illegal aliens with criminal records stay in the US

Remember the pledge that Obama made when he was sworn in as president:

I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States.

That "faithfully execute" would include enforcing laws.  Fox News has this piece commenting how Obama is selectively enforcing immigration laws.

President Obama’s new immigration plan will provide safe harbor to criminal illegal immigrants and will lead to a “capitulation to lawlessness” that could threaten public safety, Sen. Jeff Sessions, R-Ala., said.Fox News has obtained an internal document detailing how the Department of Homeland Security plans to implement what critics say amounts to an amnesty policy for what could be more than one million illegal immigrants.
According to the documents, illegal immigrants convicted of felonies or misdemeanors under “state immigration laws” may be granted deferred action. Those who have repeatedly entered the United States illegally will also be eligible. And traffic violations would not be considered a misdemeanor.
“It is a direct threat to the rule of law and to the demonstrated desire of the American people for a lawful system of immigration,” Sessions said. “I believe this administration has utilized this policy to basically undermine and negate the ability of the law officers to do what they have been hired and paid to do.” . . .
