Obama spokesman Josh Earnest also divulged that the president would host 18 Democratic lawmakers at the White House tonight to walk them through his planned actions.
Earnest told reporters that he did not anticipate that there would be any horsetrading during the dinner, as the president has already made up his mind about the bulk of his plans.
'This is more of an opportunity for the president to share his thinking with those who share his values on these issues, not really a negotiating session,' Earnest said.
One Democratic congressman with knowledge of the president's plans suggested on Tuesday night that Obama would protect parents of children who are citizens.
Senate Majority Leader Harry Reid said on the upper chamber's floor on Friday that the executive actions would affect immigrant populations who 'have deep ties in America, are law-abiding and have children or spouses who are U.S. citizens or permanent residents.'
Meanwhile, immigration groups said the White House on Tuesday held conference calls with them to alert them to the president's coming pronouncement but did not give them any specifics.
'They're setting expectations, making it clear he has the legal authority to do what he's going to do, but that he's not going beyond his authority, as some advocates would like,' a source familiar with the calls told The Hill.
Texas Republican Sen. Ted Cruz, who is among the GOP's most strident opponents of Obama's immigration approach, responded to Wednesday's news with a scathing essay in Politico, saying that the new Congress should punish the White House.
'If the President announces executive amnesty,' Cruz wrote, 'the new Senate Majority Leader who takes over in January should announce that the 114th Congress will not confirm a single nominee – executive or judicial – outside of vital national security positions, so long as the illegal amnesty persists.'
Obama's plan, he wrote, is 'lawless. It is unconstitutional. He is defiant and angry at the American people.'
'If he acts by executive diktat, President Obama will not be acting as a president, he will be acting as a monarch.'
Two House Republicans asked Obama on Wednesday in a letter to postpone his executive order, and said that they will use congressional authority to try and stop him.
'Instead of proceeding with ill-advised executive action, we implore you to work with Congress to enact legislation to address our broken immigration system,' wrote House Homeland Security Chairman Michael McCaul of Texas and House Judiciary Chairman Bob Goodlatte of Virginia.
'We strongly urge you to respect the Constitution and abandon any unconstitutional, unilateral executive actions on immigration. Let's secure the border, enforce our immigration laws in the interior of the United States, and build a broad consensus for immigration reform.'
'Otherwise,' the pair added, 'as the chairmen of the committees with oversight over border security and our nation's immigration laws, we will be forced to use the tools afforded to Congress by the Constitution to stop your administration from successfully carrying out your plan.'
The White House blew off the threats on Wednesday, pointing out that Obama could veto any sort of legislation that Congress passes curtailing his authority.
And while speaking directly about Cruz, Earnest also called on Republicans to 'put 'the interests of the nation above partisan political ambition,' just like the president is doing and has done since the midterm elections.
