USATODAY

Americans defeated President Obama's disastrous amnesty plans both in Congressand at the voting booth. Tonight, President Obama defied an entire nation and declared that he will impose his rejected amnesty through the brute force of executive order.

President Obama's executive amnesty will provide an estimated 5 million illegal immigrants with the exact benefits Congress rejected, in violation of federal law. His order will grant them social security numbers, government-issued ID's, legal status and work permits. Illegal immigrants will now be able to take jobs and benefits directly from struggling Americans in a time of high unemployment and low wages. They will be able to take jobs from Americans in all occupations, ranging from truck drivers to power company workers to jobs with city government. Many illegal immigrants will also be able to obtain green cards and become permanent residents, allowing them access to almost all federal programs, to receive citizenship and sponsor foreign relatives to join them in the U.S.

In addition to providing formal amnesty benefits for 5 million illegal immigrants, President Obama has also eliminated virtually all enforcement with respect to the other nearly 7 million illegal immigrantsin the United States. As the president's own former ICE Director, John Sandweg said: "if you are a run-of-the-mill immigrant here illegally, your odds of getting deported are close to zero."

All you have to do is get into the country from anywhere on globe — whether through the border or by overstaying a visa — and you are free to remain, take jobs and receive benefits. This year alone, the White House has released into the United States more than 100,000 illegal immigrants who simply showed up at the border and demanded entry.

And now, with a single pen stroke, President Obama is obliterating what little remains of Americans' immigration protections. Not only will millions of low-wage illegal immigrants rush into the labor market, but they will collect billions in taxpayer dollars as well. These costly government benefits range from child tax credits, to public housing to the likelihood that amnestied immigrants will rely on taxpayers for medical and retirement benefits.

Only a short time ago, President Obama himself admitted this action would be illegal and unconstitutional: "I know some people want me to bypass Congress and change the laws on my own" he explained, adding "that's not how our democracy functions. That's not how our Constitution is written." President Obama also said that: "The problem is that I'm the president of the United States, I'm not the emperor of the United States. My job is to execute laws that are passed."

Apparently, America now has its first emperor.

And he has issued an imperial order to dissolve America's borders. Millions more will enter and demand the same amnesty benefits as those who came before. The entire moral foundation and consistency of our laws will have been eviscerated. Law enforcement officials have repeatedly warned that the president's new amnesty will unleash a "tidal wave" of illegal immigration. The impact on our jobs, wages, hospitals, schools, police departments and neighborhoods will be crushing.

A second hammer blow will be dealt by the president's unilateral increase in foreign worker programs for large corporations, including technology corporations. Currently, two-thirds of all new jobs in the IT industry are being filled by foreign workers — and yet the president wants to dramatically surge foreign worker admissions even further. This at a time when the Census Bureau tells us more than 11 million Americanswith science, technology, engineering and math degrees don't have jobs in those fields.

President Obama is auctioning off America's middle class to the highest bidders.

Immigration already stands at record levels and is rising quickly. Between 2000 and 2014 — a period during which the government issued nearly 30 million lawful visas to foreign workers and permanent immigrants — all net employment gains among the working-age went to imported labor. Now the president is planning to unilaterally increase immigration even further — all to placate a few billionaire lobbyists and open border extremists.

The great task before the nation now is to resist this imperial decree and return control of this nation to its own citizens — as our Constitution established.

That task begins with Congress refusing to allow a dime of money to be spent executing this unlawful amnesty. This a routine, constitutional and crucial application of congressional power.

If Democrat lawmakers join Republicans in blocking funds for his unlawful plan, the president will be stopped. Americans must ask their representatives this one question: do you serve the citizens of this country and their Constitution — or not?
