Is it time to Impeach our President?

President Obama announced his administration will no longer enforce our immigration laws in regards to certain illegal immigrants who reside within our country.
From a news story:
 "For years the administration had said it didn’t have the authority to make such a move, saying it couldn’t decide to stop deporting wide categories of people on its own without approval from Congress.  But on Friday President Obama says administration now interprets the law to give it the discretion."
From the White House's own website it states clearly what Pres. Obama has sworn under oath do to: "Under Article II of the Constitution, the President is responsible for the execution and enforcement of the laws created by Congress." When a President refuses to fulfill the responsibilities he swore to fill, it is time for Congress to take action. But will they?  Or will they continue to complain about his outrageous flaunting of the rule of law, but allow him to continue to pick and choose what laws he will enforce.  I hope Congress will do what they must to uphold the Constitution and warn the President that if he continues to refuse to enforce laws passed by them, he has abdicated his responsibilities and must be removed from office.  Any President, no matter his party affiliation, must abide by the constraints of our Constitution, otherwise he is setting himself to be a Dictator and my hope and prayer is that Americans will not stand for that. We shall see.
