( CNN ) For President Barack Obama and the Republicans in Congress , distance does not make the heart grow fonder . With the president escaping to Asia for a critical foreign trip after last week 's bruising losses for his party , White House officials are signaling Obama will take a hard-nosed approach with Congress when he returns to Washington . Obama is `` nearing a final decision '' on issuing an executive order bringing reforms to U.S. immigration policy , White House Press Secretary Josh Earnest told reporters at a briefing in Naypyitaw , Myanmar . Earnest reiterated the President 's goal to act on the issue by the end of the year . Immigration reform advocates working with the administration on the expected executive action anticipate Obama will expand his policy of deferred deportation for undocumented children to their families , a move that may provide enforcement relief to as many as five million people . The expected incoming Senate majority leader , Republican Mitch McConnell of Kentucky , has described such a move as a `` poison pill '' that would damage relations with the new Republican Congress coming into power in January . Aides to the President brush off those GOP warnings , noting threats from Republican leaders to repeal the Affordable Care Act . Obama has vowed he will never sign that repeal legislation into law . `` Repealing Obamacare is also a poison pill , '' White House Senior Adviser Dan Pfeiffer said . Obama seeks new Syria strategy review . Earnest cited the President 's new climate change deal with China as another area where Obama can pursue his own agenda without Congress . Asked whether the administration believes the United States can meet the agreement 's carbon emission requirements without congressional involvement , Earnest said simply , `` we do . '' Administration officials believe the United States is well on its way to holding up its end of the climate deal , citing Obama 's executive decisions to raise fuel efficiency standards for cars and trucks as well as new rules that set tougher emission requirements for power plants . In his own response to the climate agreement , McConnell questioned whether China would be as ambitious . `` I read the agreement - requires the Chinese to do nothing at all for 16 years while these carbon emission regulations are creating havoc in my state and other states around the country , '' the Kentucky Republican said . Will Congress kill an Iran nuclear deal ? China would have to make `` significant '' changes in meeting its energy needs in order to comply with the deal , Deputy National Security Adviser Ben Rhodes said . On another top priority for Republicans , passage of legislation to accelerate completion of the contested Keystone oil pipeline , Earnest suggested the President is warming up his veto pen . Earnest declined to definitively say Obama would veto such legislation . But he quickly added the President has taken a `` dim view '' of similar bills in the past .
