President Obama's decision to issue an executive order without the approval of Congress is causing a firestorm across the country.
Republicans say the move is illegal. Four governors are threatening to sue the President over his plan to shield million of undocumented immigrants from deportation
But Barack Obama is not the first President to go at it alone.
CNN's Tom Foreman has the report.
President Obama is doubling down on immigration.
"I indicated to (House) Speaker (John) Boehner several months ago that if in fact Congress failed to act I would use all the lawful authority that I possess to try and make the system work better. And that's gonna happen, that's gonna happen before the end of the year," said Obama.
Congressional Republicans are vowing to fight President Barack Obama's plan to make immigration changes through executive action, but they are struggling with how to do that without triggering another government shutdown.

What is causing an influx of young immigrants to illegally cross the U.S. border? Some say it's the threat of gangs, rape and human trafficking in Central America.
Our Sara Sidner has an exclusive report - she speaks to gang members about their role in the border crisis.
America's most famous undocumented immigrant - Pulitzer-Prize journalist Jose Antonio Vargas - was released by border patrol agents Tuesday.
Vargas, who was a guest on OutFront Monday night, was arrested Tuesday morning after attempting to board a plane out of McAllen, Texas.
The Department of Homeland security released a statement saying they encountered Vargas at the airport and "apprehended him after he stated that he was in the country illegally. Mr. Vargas was transported to the McAllen Border Patrol Station where he was processed and provided with a Notice to Appear before an immigration judge."
But some are asking whether Vargas - who has been in the U.S. for more than 20 years - wanted to be detained.
CNN's Alina Machado has more.
A surge of undocumented immigrants has been coming into the United States by the tens of thousands. Many of them are children escaping dangerous conditions in Central America.
The first wave of those immigrants were deported Monday - dozens of adults and children held a facility in New Mexico were returned to Honduras.
